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. ______________________________ Sudip Kumar Bhattacharya -----Original Message----- From: Tom Evans [mailto:tevans.uk@xxxxxxxxxxxxxx] Sent: Friday, October 19, 2012 9:38 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: How to conditionally enable mod_deflate?
