Re: Shorter URLs - How?
If you are bound, bent and determined to do this in CF simply have a url parser in your app.cfc. However this is really best left to URL rewriting via the webserver.

Re: Shorter URLs - How?
IIS7 has a built in url rewriter, so no need to isapi_rewriter. It works very similar to the mod_rewrite for apache in that the rewrite rules are store din a file within your website root called web.config, so it is portable between servers running IIS7+ If you want it to be portable betweeen any server\OS then you should do it in CFML. more info: http://learn.iis.net/page.aspx/460/using-the-url-rewrite-module/ Russ On Tue, Sep 21, 2010 at 4:32 PM, Michael Grant mgr...@modus.bz wrote: Doing it with pure ColdFusion, the best thing you could hope for is http://www.scribblar.com/index.cfm/k3ns5 Untrue.

I searched for a small bit of code that Sean Corfield posted to his blog, and I can't find it. But he did add URL rewriting to his FW/1 framework. I'd wager it's close to the same code that he had separately posted earlier.

Re: Shorter URLs - How?
However this is really best left to URL rewriting via the webserver. I would also argue that it's not really bad to do URL rewriting within CF instead of in the web server. Sure, there may be high traffic situations where you're trimming miliseconds, but for most cases CF URL rewriting is a perfectly valid option. And many people would prefer to have all of their application configuration in one place, instead of needing to go to multiple places to maintain app level settings. Also, say you need to move the app to a different server or host. If you use web server URL rewriting, you'll need to set that up again on the new server. If you do it in CF you just need to drop your code on the server and your done. Personally I think it's a personal preference thing, not a This is the written in stone way that you should do it. :) ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:337273 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Shorter URLs - How?
Meh, the syntax is nearly identical between the different options. It would take anyone with half a brain all of about an hour to switch the rewrite rules over from apache to IIS or vice versa. Sure it's personal preference I guess but I generally try to use the right tool for the job. Data processing is best left to databases. URL rewriting is best left to the server. And ColdFusion server can be left to serve out ColdFusion pages. In a pinch you can use a pair of pantyhose to keep your alternator working.

Re: Shorter URLs - How?
Assuming your pages are in a database-driven system, then the custom 404 is largely just an extension of ColdFusion serving pages: which page? dunno, lemme check the aliases, ah, there it is ... this page. Web server rewrite is fine, too, but if the code is already running in CF to determine what gets served, as it is in any front-side controller framework, then it's not much different to have a custom 404 as a simpler version of the controller.

Re: Shorter URLs - How?
Not to argue, because you make good points, but just about every shared host I've ever used gives you a mechanism for url rewrite. In fact most offer really well documented steps on how to do it too. I think it's probably equally as hard for a new dev to understand url rewriting as it is to understand how to set up a custom 404 handler and then a url parser based off of the cgi scoped vars etc etc. Further I think you'd find that Google will return many many more walk throughs on web server url rewriting vs coldfusion rewriting. Six of one, half dozen of the other. I guess we'll just have to agree to disagree.

Re: Shorter URLs - How?
If you are doing it in cf then that means you are using IIS (or *nix equiv) to return a cf page for processing when it determines the file is not there. If you do it right you return the proper response in the cfheader for the url (mydomain.com/tinyurl). If you don't do it right the spider gets the content of the url that it hit but gets 404 as the response from the server. That's bad. If you rewrite using the webserver you get the same result as the 'right' approach above. At least that's my understanding.

I have done this by using a lot of session and client variables, and a settings panel that a user can set defaults with, and if there happens to be an variables passed between pages, I store them in session vars. ..tony Tony Weeg Senior Web Developer Information System Design Navtrak, Inc.

RE: Shorter urls?
simple: 1. person submits link via form to make shorter... 2. you insert data into database 3. when inserting one field called maybe unique is a random generated alpha numberic string... randomize and compare to existing data to make sure no dupe exists already... 4. write the long URL and the unique string... 5. pass the shorter back to the user.. but first: A. create an index handler that shows form if no string found otherwise looks up table entries to find match ... pauses, displays notice and then pushes them out... that's how I plan on implementing mine when I find a few hours :) -paris Paris Lundis Founder Areaindex, L.L.C. http://www.areaindex.com http://www.pubcrawler.com 412-292-3135 [finding the future in the past, passing the future in the present] [connecting people, places and things] -Original Message- From: Kevin Graeme [EMAIL PROTECTED] Date: Tue, 29 Oct 2002 12:42:58 -0600 Subject: RE: Shorter urls? http://www.makeashorterlink.com is where you've probably seen it done.

RE: Shorter urls?
Once upon a time, someone on this list described a process where they created a CFML page from IIS's 404 error page (404.html becomes 404.cfm) that pre-processes all incoming page requests. Basically, the IIS document root is completely empty and everything gets preprocessed by the 404 error file. Files get included from a CF document root to generate the actual user output. This seems like a pretty darn ingenious way to do a bunch of cool stuff! If the person who told me about this is out there, I apologize for forgetting your name!

RE: Shorter urls?
I rather assumed the caveat of the short url not being related to security... That is -- all the normal rules of security apply, and the short url does not _help_ you secure the site -- it actually doesn't really hurt in any way either, because if the short url can get someone to a place they're not supposed to be, then there is by definition, a pre-existing security error that should be fixed. Security itself should always be as close to the secured data / resources as possible. If the secured data is an individual page, security should ensure that nobody who's unauthorized for that page sees that page from that page, not for instance by removing links from other pages. This is a reasonably common mistake -- people try to secure a page by removing a link from other page(s) and someone who at one point was authorized to see the page, but is no longer authorized can still get access to it regardless by using a bookmark or typing in a url they remember.

Re: Shorter urls?
Here's an interesting solution. It's not perfect (just threw the code
together), but it works. It has the additional benefit of adding a
level of security to your application because it hashes your query
string in a way that cannot be reversed (essentially obfuscates it in a
non-reversible manner). It also assumes that once you have created a
shorter query string, you will eventually want to recover the original
query string, probably in the page processing the request that contains
the query string.
Start by including these two functions:
cfscript
function getShortString(str) {
var key = ;
if (false is isDefined(application._strMap)) {
application._strMap = structNew();
}
key = hash(str);
application._strMap[key] = str;
return key;
}
function getLongString(key) {
if (false is isDefined(application._strMap)) {
return ;
}
if (false is structKeyExists(application._strMap, key)) {
return ;
}
return application._strMap[key];
}
/cfscript
Then create your querystrings like this:
cfset qs = a=bb=cc=a /
a
href=someProcessingPage.cfm?q=cfoutput#getShortString(qs)#/cfoutputclick
here/a
In the processing page, retrieve the original querystring like this:
cfset qs = #getLongString(url.q)# /
The full querystring is cfoutput#qs#/cfoutput.
Of course, you could do something a little more clever like creating a
function that returns a struct or parses the querystring and puts the
values in the URL scope so that you could retrieve them just as though
they were literally passed in the URL as opposed to actually getting
back a query string, but you get the idea.
Your query string has to be over 32 characters before this technique
starts to pay for itself in terms of length since the hash() function
returns a 32 byte string. As I mentioned earlier, it has the added
benefit of completely obscruing the data you pass in your query string,
too, since the MD5 hash is not reversable.
If you decide to implement something like this, consider variable locking.
Hope this helps.

RE: Shorter urls?
This technique seems like a waste of processing time when the underlying
Java object already provides the same thing. From the documentation...
hashCode
public int hashCode()
Returns the hash code value for this map. The hash code of a map is
defined to be the sum of the hash codes of each entry in the map's
entrySet() view. This ensures that t1.equals(t2) implies that
t1.hashCode()==t2.hashCode() for any two maps t1 and t2, as required by
the general contract of Object.hashCode.
This implementation iterates over entrySet(), calling hashCode on each
element (entry) in the Collection, and adding up the results.
See my earlier response to the question for an example of using the
hashCode method with a Map.

Re: Shorter urls?
You could very well replace the implementation of the getShortString
function below with code which calls hashCode() on a HashMap containing
your name/value pairs, and in fact, I think it is an excellent approach.
I only opted for the hash() function in my own implementation for the
following reasons:
1. In general, calling hashCode on two distinct object instances is not
actually guaranteed to return a unique number for each object instance.
From the documentation:
It is not required that if two objects are unequal according to the
equals(java.lang.Object) method, then calling the hashCode method on
each of the two objects must produce distinct integer results. However,
the programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hashtables.
Since we are only talking about strings here, and hopefully all
implementations of Java return unique integers for unique strings
(though they are not technically required to), this is really a
non-issue. My gut reaction, though, is not to trust hashCode to always
return a unique number.
2. Since calling hashCode() on a HashMap returns the sum of all its
entries' hash codes, isn't it possible (though unlikely) that the
following statement could be true?
a.hashCode() + b.hashCode() == c.hashCode()
3. Hash codes are not guaranteed to be consistent from one execution of
a Java application to the next. From the documentation:
Whenever it is invoked on the same object more than once during an
execution of a Java application, the hashCode method must consistently
return the same integer, provided no information used in equals
comparisons on the object is modified. This integer need not remain
consistent from one execution of an application to another execution of
the same application.
In other words, if you had to restart your server, or if you were load
balancing between multiple CF servers (especially if they were running
different versions or implementations of Java), your hash codes could
technically end up being inconsistent. The implementation I provided
would need to store the struct of hashes and values persistently in
order to avoid this issue, but I believe in the end, your hashes would
be consistent.
These are really very small points which are very unlikely to occur, so
in general, I agree with Matt that his implementation is a good
approach. And I also agree with him that calculating a hash code should
be (though is not guaranteed to be) less processor-intensive than the
MD5 algorithm. I only meant to suggest an alternative.
