I have mod_autoindex and mod_filter in use. Filter configuration: FilterDeclare compressit FilterProtocol compressit change=yes FilterProvider compressit DEFLATE resp=Content-Encoding !$gzip FilterProvider compressit DEFLATE resp=Content-Type $text/html FilterProvider compressit DEFLATE resp=Content-Type $text/plain FilterProvider compressit DEFLATE resp=Content-Type $text/xml FilterProvider compressit DEFLATE resp=Content-Type $application/x-javascript FilterChain compressit If I have a directory with a .htaccess file that contains HeaderName foo.html then the directory listing is correctly displayed in the browser, *but* the content is not compressed. If the HeaderName directive is commented out of the .htaccess file, then the directory listing *is* compressed by the mod_filter / mod_deflate combination. A quick look at the code in mod_autoindex.c reveals some alarming comments in function 'emit_head' which is where I suspect that the problem lies. I have no idea what the fix is.......
According to the source, this still applies to 2.4.6.
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.
I was able to reproduce this issue with Apache/2.4.25 (Debian).
