Using SetEnvIf for QUERY_STRING

[Mohit Chawla <mohit.chawla.binary@xxxxxxxxx>]

Hi, 

I am trying to use SetEnvIf with QUERY_STRING, but can't get it to work. This is being done inside the mod_deflate module block like: 

<IfModule mod_deflate.c>

SetEnvIf QUERY_STRING foo var=bar

LogFormat '"%q" "%{var}e"'

</IfModule>

...with a request like curl localhost?baz, the log has: 

"?baz" "-"

Other variables like REQUEST_METHOD work fine: 

<IfModule mod_deflate.c>

SetEnvIf REQUEST_METHOD GET var=bar

LogFormat '"%q" "%{var}e"'

</IfModule>

$ curl localhost?baz

"?baz" "bar"

Apache version is 2.2.22 on Ubuntu 12.04. 

Any ideas how to debug or fix this ? 

Thanks, 

Mohit
