What hoolio says is true, but in this case it isn't HTTP code inserting the Vary header, it's the compression code. So I don't think you'll be able to remove it in HTTP_RESPONSE. You could remove it in HTTP_RESPONSE_RELEASE if your version supports that event, but if your compression settings are still in your http profiles, then you're likely still on a 10.x or earlier release, which doesn't. What version are you on?

 

 

You might be able to solve the problem by calling COMPRESS::disable explicitly in HTTP_RESPONSE if the response will never be compressed.

 

 

Worst case, you could use a VIP-targeting-VIP, configure compression on the "internal" (non-customer-facing) VIP, and remove the header on the "external" (customer-facing) VIP.

 

 

I'll check with some other people to see if they have some idea about configuring the compression settings to solve or mitigate this issue.
