Hi Tom,
Here is how I have the setup currently on the original apache. GZIP is enabled,
and turned off for specific file types.
######20121011 SKB to test optimization
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png|swf)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip
dont-vary
SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
######
The flag to determine whether the access is being made via the proxy is
RequestHeader set RemoteUser "remote"
Now on the original apache, I want to disable GZIP when RemoteUser Request
Header is not present in the request.
Can you please help with the syntax of SetEnvIf to set no-gzip if the request
header is not present.
Somehow, I am able to check the Request_URI header, but not my custom header,
which is being added from the proxy apache.

Enable mod_deflate, and use mod_setenvif, mod_headers or mod_rewrite to set
either the environment variable "force-gzip" or "no-gzip", as documented on the
mod_deflate manual page.
