[twsocket] ICS Wiki : author wanted
Hi ! As you probably know, we have a Wiki for ICS documentation: http://wiki.overbyte.be A wiki is a collaborative tool. We already have a few authors writing articles. Actually not that much ! If you have some spare time, please use it to write some article in the wiki. If each ICS user write only a single page, we will have tens of thousands pages ! No need to know everything. It is enough if you know ONE thing. Just write a page and you'll enter the hall of fames :-) To collaborate, just login onto the wiki and email me the usercode you selected. I will give you write permission. Thanks a lot. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] FileMD5 : Different Hash Result - same File ondifferent workstation
Phhh.. I just got back. Face this: On this client some files (not all!) had a different md5 hash. But this everytime with all tools! After a while i did a reboot - and guess: everything was as expected. Maybe Piotr was right with some harware issue. Very very strange! Whatever. I wrote this tool to check FileMD5 with ICS_V6, ICS_V7 and INDY_10. It display's the result in a memo with time measurement.

Re: [twsocket] FileMD5 : Different Hash Result - same File ondifferent workstat
If your intent is to benchmark the speed of different MD5 implementations You also have to allow for file caching. I added buffered file access to the ICS v7 hashing units recently, and the difference between the first and subsequent runs can be 50 times different, once the file is cached by Windows.

I think you should try our tool as well with ICSv6 as it also has file buffering.

I guess that this could replace the buffered stream IO and make it even faster, provided Chunksize was large enough. Knowing the Chunksize would IMO also ease and speed up progress calculations in a callback routine, ProgressBar isn't aware of int64. -- Arno Garrels -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Converting an IIS/ASP3 site to an ICS web application
I've just finished converting a 10 year old web site that previously ran
on Microsoft IIS to a full Delphi web application using the new
THttpAppSrv web application server, and thought some comments might be of
interest.
Old Technology
--
The old site ran on Microsoft IIS/5/6/7 using ASP v3 VBScript pages,
supported by Delphi COM objects for DNS lookups and non-SQL database
lookups, and a Delphi ISAPI Filter (PassDir) for authentication
restricting paid members to certain sub-directories. It also used
various Microsoft COM objects, to send email, look-up file tile stamps,
etc. Many of the site static pages were created offline by a Delphi
application from a non-SQL database, originating from various CSV, HTML
and Excel files.
The site was originally on a shared web server at a hosting facility that
allowed COM objects and filters to be installed, which not everyone does.
The original site is at:
http://www.magsys.co.uk/telecom/
New Technology
--
The new site is a Delphi web application, written with ICS v7 and Delphi
2007, using the THttpAppSrv, THttpServer and TSmtpCli components.
The new site is on my own hosted server (as is the old site now) at:
http://www.telecom-tariffs.co.uk/
The main reason for the conversion to Delphi was maintainability. The
old site had a mix of technologies and languages, and updating the COM
objects and ISAPI Filters was not easy. I did look at converting to
ASPX/.NET using Delphi .NET or Prism, but it's a major learning curve
with a massive rewrite necessary, and dependence upon ever changing
Microsoft runtimes. I do have a commercial .NET application on my server,
and it takes up to 30 seconds to wake up and offer the index page, unless
accessed regularly to keep it in memory.
Create a Web Server
---
Before the site could be converted, I needed a base web application
server, which means hanging a lot of code around the THttpServer
component. Servers must run as Windows services, and I use the proven
SvCom environment that allows debugging and running under Delphi and
deployment as a service. I added a configuration file, debug log files,
and W3C extended log files acceptable to web statistics analysis
applications. I had to update both OverbyteIcsHttpSrv and
OverbyteIcsWSocket to get an event showing how much data was actually
sent to the client when the request completed and with the result code. I
also added content encoding since some of my static pages are 300K of
HTML that compress down to 20K, speeding up downloads.
Converting the Site
---
ASP pages generally comprise both server side code (VBScript) and the
HTML and often client side code (Javascript) in the same file, in the
public web directory. An ICS web application still has a public root for
static HTML pages, images and other files, then a template directory for
dynamic pages comprising pure HTML and server side code, with the server
side code in a Delphi unit.
My ASP included dynamic content with the HTML tag %=name% where name
could be a variable or function name. For ICS, these tags become #name
which are replaced by the ICS function HtmlPageProducerToStream with
application content. I also have server side includes (SSI) in ASP pages,
ie !--#include file=addcopy.inc-- inserts a file at that point in the
page, which I changed to #addcopyinc and then loaded the file into a
string of similar name which is returned dynamically.
Each dynamic page with a template needs a matching UrlHandler class:
TUrlHandlerTcomlink = class(TUrlHandler)
public
procedure Execute; override;
end;
which is added to the application server GET or POST lists:
AddGetHandler('/tcomlink.htm', TUrlHandlerTcomlink);
then the actual code is simple for this page which shows the file time
stamp for the template, and two SSIs:
procedure TUrlHandlerTcomlink.Execute;
begin
AnswerPage('', NO_CACHE, 'tcomlink.htm', nil,
['PageLastMod', GetTempLastMod (Client, 'tcomlink.htm'),
'OtherLinksInc', SsiOtherLinksInc,
'AddCopyInc', SsiAddCopyInc ]);
Finish;
end;
GetTempLastMod is a function that checks the file and format the date
into a string. In the response, NO_CACHE is literal for a header to stop
the page being cached, but other for pages I add cookies to this header.
The [] parameters are paired, first being the tag name, then the variable
for replacement, three in this example.
Other pages need more complicated UrlHandlers, the web application has a
server information page at:
http://www.telecom-tariffs.co.uk/serverinfo.htm
that uses TWSocket and a timer to look-up the client host name with a
five second timeout to avoid long DNS delays:
TUrlHandlerServerInfo = class(TUrlHandler)
private
WSocket: TWSocket;
AbortTimer: TTimer;
sIPAddr: string ;
sUserIPHost: string ;
public
destructor Destroy; override;
procedure Execute; override;
procedure
