Log file problem

[PremiumSaltine]

I'm currently using "SetEnvIf Request_URI "blahblah" dontlog" for simple requests, however I have more complex requests I'm having troubles filtering.

GET /p/index.html?cmd=thumb&sfpg=MjAwNS8wOS8qMDAwXzA0NzYuanBnKjU3ZjMyMjc0NDg5YTdiMTVhM2RkNWE4NWI4ZWZjYWYw
GET /p/index.html?cmd=photo&sfpg=MjAwNS8wOS8qMDAwXzA0NzYuanBnKjU3ZjMyMjc0NDg5YTdiMTVhM2RkNWE4NWI4ZWZjYWYw

I would like to filter out just the requests with "cmd=thumb", but i can't quite figure out how to do it. Please help me out here. Thank you.

Does Query_String work? Apache cops out by pointing you from mod_setenvif to mod_rewrite, but that seems to be what they're saying. And if that's not what they're saying, you can use mod_rewrite itself to set an environmental variable (flag [E=something] or [E=something:value]) and take it from there.

I'm so confused by what you said. I am pretty n00bish to this. All I'm trying to do is get the requests that contain "cmd=thumb" to not show up in my access log.

The "cmd=thumb" element is in the query string, not in the body of the URL, so you have to use different wording.

You're currently using

SetEnvIf Request_URI

so I wondered if

SetEnvIf Query_String

would work. Can't test it myself because I don't use query strings except internally, but someone should know.

:: looking vaguely around for g1 or someone like him ::

And if you can't do this with mod_setenvif, the alternative way using mod_rewrite should be straightforward.
It may help to remember that the environmental variable by itself (in this case "dontlog") doesn't do anything. It's just a way of carrying a message.

I couldn't get the SetEnvIf Query_String idea to work.

I did try this, but it got me nowhere:

RewriteCond %{QUERY_STRING} ^cmd=thumb$
RewriteRule (.*) $1 [E=dontlog:yes]

[lucy24]

Is "cmd=thumb" the only thing in the query string? If not, the ^ $ anchors will prevent it from working.

[PremiumSaltine]

I took the two anchors off and it works. Thank you so much!
