Hi everybody,
I am struggling a bit with an issue around (apache) environment
variables. I am using an environment variable for logging purposes and
everything works fine, except in the case of an request for a
mod_userdir resource (e.g. GET /~username/something.html) that fails
(e.g. response code 404).
I set the variable USERPAGE_USER via SetEnvIfNoCase or RewriteRule and
can see that it is correctly set using directives like
RewriteCond %{ENV:USERPAGE_USER} ^(.+)$
RewriteRule ^.*$ - [E=FOUND_USER:%1]
and watching the rewrite.log file of mod_rewrite.
However after the internal redirect to the ErrorDocument handler (a cgi
script) but before the handling of this request this environment
variable is cleared.
To make it clear. It works for me if
* the request is successful (200)
* the request is not a UserDir-request (not ~username) and fails
* the request is not a UserDir-request (not ~username) and succeeds
My Apache version is: 2.0.54
Down is a sample log part (sorry it's ugly).
Can you see any reason for that?
Do I do something wrong?
Thanks in advance,
jan
