Summary: Content-Encoding value returned by apache is malformed
Product: Apache httpd-2
Version: 2.2.3
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_deflate
AssignedTo: [email protected]
ReportedBy: [email protected]
This bug occurs on a site running the MediaWiki software and occurs for both MW
1.13.2 and 1.16.2. When a request to download a file is received, apache
returns a malformed Content-Encoding header value of ", gzip". This befuddles
some browsers (e.g., Safari, IE and Firefox), while others seem to silently
discard the leading comma (Opera and Chrome). The result is the file is
delivered to the host file system by the confused browsers in compressed form.
Since the site uses Squid, I confirmed that the problem also occurs when Squid
is bypassed.
Note: I attempted to read the bug writing help page
https://issues.apache.org/bugwritinghelp.html as I am a new bug reporter.
However, the link returns a 404 Not Found error. Here is some relevant
information that I can only suppose is useful:
Apache version: 2.2.3
PHP version: 5.3.5
OS: CentOS 5.5
Browser: various - example is for Firefox 3.6.13 running on Mac OS X 10.6.6
Here is the request and response headers (I have obscured some file and
cookie information using ellipses to ensure privacy - the output is from
HTTPFox running on Firefox):

Note that the Accept-Encoding header in the request specifies "gzip, deflate",
while the Content-Encoding value in the response is ", gzip". I posted a query
about the problem on
http://groups.google.com/group/comp.infosystems.www.servers.unix, but did not
receive a response. (I posted the query over three weeks ago).
