title: Apache Webserver: check if decompression on
body: <p>With <code>SetInputFilter DEFLATE</code> I can force the apache to decompress incoming messages. Is there a way to ask the webserver whether it supports decompression of incoming request. I would expect a specific HEADER information for that. 
  The only HEADER information I know of is: accept-encoding (which is for requests, afaik) and content-encoding (which only tells the client that the response is encoded right?).</p>
