Bug ID: 58828
Summary: LA-U variables not set depending on the URI
Product: Apache httpd-2
Version: 2.4-HEAD
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: mod_rewrite
Assignee: [email protected]

Hello,
I think I found a bug where %{LA-U:VARS} variables are not correctly set,
depending on the URI.
Here is the configuration I use, which gives an authenticated user ($1) its own
files ($2) :
DocumentRoot /users/www/default
<Directory /users/www>
Options Indexes
AuthType Basic
(...)
Require valid-user
</Directory>
RewriteCond $1:%{LA-U:REMOTE_USER} ^(.+):\1$
RewriteRule ^/([^/]+)/(.*)$ /users/www/$1/$2
Here is my test directory structure :
/users/www/testuser/foo%1
/users/www/testuser/foo%10
foo%1 results :
"GET /testuser/foo%251/ HTTP/1.1" 404
File does not exist: /users/www/default/testuser/foo%251/
foo%10 results :
"GET /authuser/foo%2510/ HTTP/1.1" 200
I then tested some other directory patterns :
- work : "foo%1bar"
- don't work : "foo%2", "foo%3", ..., "foo%9", "foo%1 bar"
I then found that for failing patterns, %{LA-U:REMOTE_USER} is empty :
If I use the following less restrictive condition, patterns still fail :
RewriteCond $1:%{LA-U:REMOTE_USER} ^(.+):(.+)$
But if I use the following one (allowing empty var), then all patterns are OK :
RewriteCond $1:%{LA-U:REMOTE_USER} ^(.+):(.*)$
I then tested the following condition :
RewriteCond $1:%{LA-U:REQUEST_FILENAME} ^(.+):(.+)$
Failing patterns still fail !
And with the following one :
RewriteCond $1:%{REQUEST_FILENAME} ^(.+):(.+)$
All patterns are correctly rewritten !
Is there an issue with mod_rewrite and LA-U on some URI patterns ?
Could you help me finding the issue / patching the code please ?
Thank you very much !
Ben
