Occasional HTTP Error 404 - File or directory not found

jweber · #1 (**permalink**) 06-19-2008, 07:27 PM

Sometimes I get a 404 error returned from the server when making a request to a module other than the default module (I am using the conventional modular layout). The error does not occur often, once every three weeks or so.

The web server is running IIS 6, and I am using a pretty standard Isapi_Rewrite rule. The 404 from the server suggests to me that for some reason the request is not getting sent to the bootstrap file for all requests to modules other than the default.

IIS logs just show a 404 error as expected, and the Windows Event Viewer does not show anything.

I am currently using ZF 1.5.2, though this has always been an issue.

Closing the browser and reopening the browser fixes this seemingly random problem, until it occurs again.

Any thoughts?

Are any other ZF developers experiencing this issue too?

Problem solved. Had to do with a rewrite condition that was getting met when the auth ticket began with a certain character.

Hi jweber,

Could you please post your rewrite condition and rule here? I'm also facing similar problem.

Thanks

Here is my rewrite for ISAPI_Rewrite 2:

Code:

[ISAPI_Rewrite]
# UFCD /Intranet/ZF rewrite for Zend Framework 1.5.1
#
# Author: Justus Weber
# Copyright: 2008 UFCD

# turn on the rewrite engine
RewriteEngine on

# only rewrite requests when the intranet auth cookie is set
RewriteCond Cookie: .*UFCDIntranetAuth=.*

# only rewrite requests made to the correct subdirectory
RewriteCond URL (/intranet/ZF/.*)

# perform the rewrite
RewriteRule ^[\w/\%]*(?:\.(?!(?:js|ico|gif|jpg|png|css)$)[\w\%]*$)? /intranet/ZF/index.php [i]

and here is the same for the serving running ISAPI_Rewrite 3:

Code:

# Helicon ISAPI_Rewrite configuration file
# Version 3.0.0.25

RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
RewriteBase 

# 
#  Author: Justus Weber
#  Copyright: 2008 UFCD

#  only rewrite requests when the intranet auth cookie is set
#  only rewrite requests made to the correct subdirectory
#  perform the rewrite
RewriteCond %{HTTP:Cookie} ^.*UFCDIntranetAuth=.*$ [NC]
RewriteCond %{REQUEST_URI} ^(/intranet/ZF/.*)$ [NC]
RewriteRule ^[\w/\%]*(?:\.(?!(?:js|ico|gif|jpg|png|css)$)[\w\%]*$)?$ /intranet/ZF/index.php [NC]
