Description Tomas Forsman 2013-05-13 11:04:17 UTC
Similar to bug 43939, having mod_deflate and mod_mime cooperating can give broken output.

Working version:
test1.html containing:
<!--#include virtual="test2.html"-->

test2.html containing:

<gzip compressed>test1-before


Malfunctioning version, only change is the renaming of test2.html to test2.html.utf8:
test1.html containing:
<!--#include virtual="test2.html"-->

test2.html.utf8 containing:

Result (note the wrong order and the mix of compressed and not):
<gzip compressed>test1-before


The same problem shows up when doing includes with language-dependent extensions, like test2.html.en and test2.html.sv and then doing include on test2.html .

Configuration data:
AddType text/html .html
AddOutputFilter INCLUDES .html
AddOutputFilterByType DEFLATE text/html
AddCharset UTF-8       .utf8

Tested on Debian7/Wheezy AMD64, apache 2.2.22-13 with prefork MPM.
Comment 1 William A. Rowe Jr. 2018-11-07 21:08:07 UTC
Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd.

As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd.

If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question.

If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with.

Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
