Re: Comprehensive article on how CFID and CFTOKEN work?
I'm building a cart-like application where I intend to store the (usually anonymous) user's intra-session web site state in a database table. Using cfid and cftoken are the obvious choice to use to ID a given user's state (I do realize that it would be system-unique and wouldn't follow the user across computers, which is fine) when stored in the database, but I feel like my understanding of how (and when) CFID's and CFTOKEN's are created is incomplete. Is there a comprehensive guide to the how's and why's of cfid and cftoken available online? Thanks, Pete Pete, I'll take a crack at this based on all that I recall and about 14 years of experience with ColdFusion. =) CFID and CFTOKEN are set as persistent cookies by ColdFusion. This means that, assuming the end user has cookies enabled, the cookies are set and will retain the originally set value until they are specifically cleared by the end user. So, if a user visits your site for the very first time, ColdFusion will assign a new set of CFID and CFTOKEN values via a pair of cookies. CFID is assigned sort of like an identity or autonumber, while CFTOKEN may be set in two different ways. By default, CFTOKEN will be set as an 8-digit random number. However, there's an option in the ColdFusion Administrator under the Settings menu to assign CFTOKEN as a UUID instead of a random number. And if you're dealing with a cluster of servers that might have unique host names but the same domain name, there's a boolean argument for the cfapplication tag called setdomaincookies (default: false) which will set the CFID and CFTOKEN cookies as domain-level cookies so that any hostname on that domain can read/write/share them. Back many years ago, it used to be that there was a section in the registry where the seed value for CFID was stored and could be altered or reset. These days, I'm not sure off the top of my head if that still exists.

RE: fieldnames structure
Deana, You're close. The FORM scope itself is actually just one big structure, which means you can copy it and pass it along. You'll likely, however, need to convert it to something that can be passed in the form hidden field - I'd recommend WDDX. Try something like this. !--- copy the form scope from the previous page submission --- cfset stcPage1 = structCopy(form) !--- encode it as a WDDX packet --- cfwddx action=cfml2wddx input=#stcPage1# output=wstcPage1 !--- embed it in the form on page 2 --- cfoutput input type=hidden name=stcPage1 value=#wstcPage2# /cfoutput This will pass the struct as a WDDX packet named wstPage1. In order to access the values of the struct on the next page, you'll need to de-serialize it first, like this (this would be in the submit logic on page 2): cfwddx action=wddx2cfml input=#form.wstcPage1# output=stcPage1 Then you should be able to reference fields from page one in the following manner: cfoutput #stcPage1.strFormField1#br #stcPage1.strFormField2#br /cfoutput Hope this helps, Tyson -Original Message- From: Deanna Schneider [mailto:[EMAIL PROTECTED]] Sent: Friday, August 31, 2001 10:38 AM To: CF-Talk Subject: fieldnames structure Hi Folks, I'm trying to figure out this structure thing, and I have a project where I have to grab all the fieldname/value pairs from one form, hold them while the user fills out a second page, then send them along in a hidden field to the action page.

RE: IIF and DE
Not exactly. IIF() creates an IF/ELSE scenario which, technically speaking, could be considered two statements even though only one of them actually has a condition defined. Fact of the matter is, this comes down to what's called short circuit logic. In most languages in any if/else pair, once a match with one of the if clauses is established, the rest of the if/else statement is simply ignored - commonly referred to as short circuiting. You'll find that ColdFusion works this way with CFIF, CFELSEIF and CFELSE. However, in the case of IIF(), ColdFusion doesn't short circuit which means that it tries to validate the entire statement block, even though only part of it actually needs to execute. Consider the following two code examples. The first one will run without any errors, but the second one, while performing the same logic, will fail. This is because the first scenario gets short circuited and the second one does not. ---[ begin example 1 ]--- cfset strFoo = foo cfif isDefined(strFoo) and len(trim(strFoo)) cfoutputstrFoo = #strFoo#/cfoutput cfelse cfoutputstrFoo2 = #strFoo2#/cfoutput /cfif ---[ end example 1 ]--- ---[ begin example 2 ]--- cfset strFoo = foo cfoutput #iif(isDefined(strFoo) and len(trim(strFoo)),de(strFoo),de(strFoo2))# /cfoutput ---[ end example 2 ]--- Hope that makes sense and/or helps. :) -Tyson -Original Message- From: Brent Goldman [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 29, 2001 8:05 PM To: CF-Talk Subject: RE: IIF and DE Hi, Good idea, but I think you missed the problem.

RE: IIF and DE
Dave,
Maybe it's just me (it's still early), but I don't understand how your
example with evaluate() can be considered a workaround for a parameter that
doesn't exist. Using the example you specified still results in the same
error. Here was Brent's original code (the source of this whole thread):
cfset orderString =
iif(isDefined(attributes.order),DE(amp;order=#attributes.order#), )
cflocation url=index.cfm?fuseaction=tools#orderString#
If I'm understanding your workaround example correctly, here's what you're
proposing instead:
cfset orderString =
iif(isDefined(attributes.order),DE(#evaluate('amp;order=#attributes.orde
r#')#), )
cflocation url=index.cfm?fuseaction=tools#orderString#
Both of these code example produce the exact same result - Error resolving
parameter attributes.order
Am I missing something? :)

Tyson

Subject: RE: IIF and DE
ColdFusion doesn't validate the entire statement block per se, it's just
that the variables you pass in are parameters to a function and have to
exist in order to pass in. Hence the workaround I sent before of using
evaluate().
Other languages that short circuit in if/else if/else blocks still have to
have variables defined in order to pass into functions - there's no magic
there - it just skips the rest of the block once it matches a condition
specified. The compiler will complain if the variables aren't defined ahead
of time in languages like C, C++, Java, etc., and since you don't have the
option of compiling ColdFusion (as far as I know, anyway) to rid yourself of
errors like this, you hit the problem at run-time. IIF does in fact short
circuit like it's supposed to.

Subject: RE: IIF and DE
Not exactly. IIF() creates an IF/ELSE scenario which, technically speaking,
could be considered two statements even though only one of them actually has
a condition defined.
Fact of the matter is, this comes down to what's called short circuit
logic. In most languages in any if/else pair, once a match with one of the
if clauses is established, the rest of the if/else statement is simply
ignored - commonly referred to as short circuiting. You'll find that
ColdFusion works this way with CFIF, CFELSEIF and CFELSE. However, in the
case of IIF(), ColdFusion doesn't short circuit which means that it tries to
validate the entire statement block, even though only part of it actually
needs to execute.

RE: shopping cart / online store
Actually, the argument here goes both ways. On one hand, you could code all your queries into stored procedures. In this manner, database operations typically end up performing faster than they would with inline ColdFusion cfquery statements. However, if you want to port your ColdFusion code to a different RDBMS (i.e. MS SQL Server to Oracle), then you'll likely have to re-write all the stored procedures per Oracle's standards. Additionally, if your ColdFusion developers do not have access to directly modify the stored procedures (sometimes only the DBA will have these rights), then making a change to a database call now involves more people and typically takes longer to complete. On the other hand, you could code all your queries into the ColdFusion code. In this manner, the queries will not run as fast, but any developer with access to change CFML code with also have direct rights to change database calls - eliminating the possible bottleneck mentioned above with getting a DBA involved. However, now if someone wants to port the application to a different language (i.e. ASP, PHP, Perl, whatever) or perhaps build an add-on application that points to the same database, you've now got to re-write all that database business logic in the new language or the new application. That said, as a developer you really have to weigh this against what best suites your needs. Perhaps you're dealing with a low volume site on a hosted server where you don't have rights to create/update stored procedures. In that case, it makes more sense to build your database logic in-line with cfquery statements. However, if you're dealing with a high-traffic site with tons of simultaneous users and have rights to create/update stored procedures (in addition to the knowledge of how to actually write them), you'd probably be best off writing your database logic into stored procedures. Either way, if you shift the RDBMS or the language of the application, you're going to run into some need to change large portions of logic - whether it's in stored procs or it's in ColdFusion code.

By writing the queries in the program itself (included as a query file or in the actual file, whichever), you're not quite as locked into the database - as long as you're using a relational database that supports SQL standards and you write standard SQL, you should be ok to plug and play databases as you please - stored procs screw that all up. Another problem with putting too much business logic in stored procedures is that you put too much strain on the database if the site is hit hard - I worked on a site that gets upwards of a million hits a day (www.casio.com) and using stored procedures to do too much business logic would have bogged down the database servers far too much to make it worthwhile.

RE: Encryption differences in ColdFusion 4.5 and 5.0?
Technicalities aside, I totally agree with your general point here, Ray.
Anyone who uses undocumented features of an application, ColdFusion or
otherwise, runs the risk of finding themselves in a bind when future
revisions and releases are made with the potential of changing or
eliminating those features. I preached the same thing about Spectra when
people immediately wanted to make changes to the customtags and COAPI. I'm
on your side of the fence on this one. This is a fundamental concept of
best practices that developers should never ignore.
Put simply, the fact that a search on the Allaire ColdFusion Support forums
on the keywords encrypt and decrypt returns numerous messages outlining
this very same problem indicates that this IS an issue - at least for some
developers. However, I'll add that I did some rigorous testing of this
issue last night on my system at home under ColdFusion 5.0 and was unable to
produce any of the error messages that were claimed under ColdFusion 4.x -
perhaps the problem was solved with the release of 5.0? I wrote a script
the ran high numbers of loops creating encrypted string, inserting them into
a simple database table, retrieving them, decrypting them and displaying
them. I was able to do this over 1,000,000 times without causing any errors
indicating that The data to be decrypted is invalid. But, I do remember a
time in the past on a previous project where we ran into these errors while
encrypting strings with ColdFusion 4.x versions.

RE: Encryption differences in ColdFusion 4.5 and 5.0?
Ray and all,
The issue with the out-of-the-box ColdFusion encrypt/decrypt functions is
that it doesn't limit itself to safe characters when doing the encrypting.
Specifically, there's the possibility that the encrypt() function will
generate an encrypted string with single quotes ('), spaces ( ), pound signs
(#), line feeds or line breaks.Once an encrypted string with any of
these characters has been generated, it can cause problems when trying to
decrypt and get the original string. In some cases, this throws the
all-too-familiar The value to be decrypted is not valid error message.
Most of the time, this occurs when you take your string, encrypt it, stuff
it into the database, retrieve the value from the database and attempt to
decrypt it.
If the encrypt() function were a little less dangerous, perhaps more people
would use it. The headaches caused by this function can also be evidenced
by going to the Allaire site and searching the ColdFusion Support Forums for
encrypt and decrypt - you'll find tons of messages that describe this
very same problem and recommend, as an alternative, to use the undocumented
cfusion_encrypt() and cfusion_decrypt() functions.
Unfortunately, the release of ColdFusion 5.0 apparently has not corrected
this problem either.
Hope this helps,

RE: Looping through lists
Chris, I agree with some of the other comments that your database design might need some work, but as an answer to your question I'll propose this. Say your form has a field called FORM.strKeywords which is the field in which the user will type a set of keywords separated by spaces. Here's what you'll want to do on the page that the search form submits to: !--- find all records with matching keywords --- cfquery name=qSearch datasource=yourDSN SELECT id , strName , strKeywords FROM tblYourTableName WHERE 1=1 cfloop list=#trim(form.strKeywords)# index=keyword delimiters= AND strKeywords LIKE '%#keyword#%' /cfloop /cfquery Of course, this will only find records which match ALL of the keywords a user entered. I think you should be able to figure out how to adapt this to finding ANY matching records if that's what you wanted.

In the data base there is a KeyWords field which contains a comma delimited list of keywords for each entry. I have a query which loops over the form text box entries. How do I then loop over the database keyword fields to check for a match? I am a little stuck. Any suggestions, code snippets, links to sites would be greatly appreciated.

RE: cfhttp Connection failure
The server that the CFHTTP call is running from might not have DNS available. If you're CFHTTP call is pointing to a domain name (i.e. www.amazon.com) rather than an IP address (i.e. 198.24.182.3 - made that up), the server issuing the CFHTTP call has to be correctly configured to use DNS in order to resolve the www.amazon.com into the IP address. Without it, ColdFusion will never make a connection to the page and, if you haven't set a timeout on the CFHTTP call, will permanently jam one of your running request slots in CF.

RE: Open Source Content Mananagent System
It's 98% open source. There are certain files related to security function which are cfencoded. Most of these pertain to security procedures, interactions with LDAP, etc. Other than that, all of the CFML code for Spectra is open source. Additionally, there are also guidelines on how to go about implementing your own changes to Spectra. However, beware of changing Spectra too much if you've paid for a support agreement of the product. Once you start making changes, you'll have a very tough time convincing support to even come near you... and rightly so. -Tyson -Original Message- From: Alex [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 21, 2001 12:19 PM To: CF-Talk Subject: RE: Open Source Content Mananagent System is spectra open source? ~~ Structure your ColdFusion code with Fusebox.

RE: Search Safe String - How-To?
Try using the urlEncodedFormat function. This would convert your string of... news/worldnews.cfm ... into something like this ... news%2Fworldnews%2Ecfm That would do the trick. -Tyson -Original Message- From: David Grabbe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 21, 2001 2:08 PM To: CF-Talk Subject: RE: Search Safe String - How-To? I understand that in order to make a URL search engine happy it can't contain the '?' or '' charactersall of the solutions I have seen revolve around replacing those with the backslash. I'm running into a problem, though, because the values of my URL variables regularly have a backslash in them already -- to delineate a directory on the web server: http://www.domain.com/home.cfm?page=news/worldnews.cfmlang=en ...and so forth. (Every page is based off the 'home.cfm?page=foo.cfm' template, for ease of including a header, navigation, etc). so the backslash in 'news/worldnews.cfm' is throwing me a curve. I've 'inherited' this site -- not sure if this architecture is a good one or not. Its great because of the template structure, but now that i'm trying to optimize it for search engines, its becoming a pain because of the directory notation. Any suggestions for fixing the URLs for the search engines and/or the underlying structure of the site?

RE: CFHTTP inside a huge loop
I smell major kludge here. Is there anything you can do in order to avoid running 1 CFHTTPs? Does this run often? Could you break it into smaller chunks? Could you load information into a database and query it instead?
