Bug 56354

Summary: If-None_Match fails for gzipped content
Product: Apache httpd-2 Reporter: Jesús Cea <jcea>
Component: AllAssignee: Apache HTTPD Bugs Mailing List <bugs>
Status: RESOLVED DUPLICATE    
Severity: normal CC: jcea
Priority: P2    
Version: 2.4.7   
Target Milestone: ---

OS: Solaris   

Description Jesús Cea 2014-04-07 03:05:40 UTC 
Apache 2.4.9 affected, but the selector only allows me to flag 2.4.7.

When I do a GET of a resource with "accept-encoding: gzip", I get a compressed version and a ETAG like "2bc8-4f63627bade04-gzip".

If time after that I repeat the request with

  If-None-Match: "2bc8-4f63627bade04-gzip"

I get a 200 again!, sending the content back again.

If, instead, I do a:

  If-None-Match: "2bc8-4f63627bade04"

I get the correct 304, no changes.

So, looks like Apache is adding "-gzip" suffix to the ETAG, but it is not verifying it when it gets a "If-Modified-Since".
