Inconsistent ColdFusion redirection

[Millsy Profile]

Hi All,

I'm running ColdFusion9 standard, Windows 2003 R2 and IIS6.0 plus .NET 4.0.30319, all with "vanilla" installs. On top we're running ISAPI_rewrite Version 3.1.0.79.

I have a very basic application intended to function as a mimic of TinyURL. All pages/requests outside the /admin folder should be redirected to a specific .cfm page in the root level. Pages inside the /admin folder should be allowd to process as normal. The redirection itself seems to be working fine - too well in fact

Everything works properly in both my development and test environments. On my production environment redirects randomly affect SOME of the pages in the /admin folder and not others (it should be none at all by my rules). There is no rhyme or reason I can see, having checked all three systems are consistent in terms of codebase, .htaccess, permissions, etc.

Here is my .htaccess file:

# Helicon ISAPI_Rewrite configuration file
# Version 3.1.0.79

RewriteEngine On
RewriteCond %{URL} ^(?!/(admin.*)$)
RewriteRule ^([A-Za-z0-9]*)$ redirect.cfm?s=$1 [NC,L]

I turned logging on and could not see anything wrong.

Here's a sample of the log for a request:

192.168.20.250 192.168.20.250 Tue, 17-Apr-2012 11:17:58 GMT [<domain removed>/sid#7251][rid#20521488/initial] (2) init rewrite engine with requested uri /admin/dspCreate.cfm

I've tried the advice here http://www.helicontech.com/articles/adj ... aboration/ to no avail.

Have I missed something? Has anyone else experienced this problem?

Thanks in advance for your help.

Cheers,
Millsy

Hello,

You've missed the best part in the logs, where the fun starts. Please, provide some more of the very request.

In the meantime, try using the following condition instead:

Code: Select all

RewriteCond %{REQUEST_URI} !^/admin.*$ [NC]

Regards
Andrew

Thans for your help. I've worked out the issue. It was an obscure permissions issue with Windows.
