Bug ID: 63282 Summary: Cache keys incorrect on rewrite Product: Apache httpd-2 Version: 2.4.38 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P2 Component: mod_cache_disk / mod_disk_cache Assignee: bugs@httpd.apache.org Reporter: adam.v...@vestfarms.com Target Milestone: --- Hello all, I've been working at this for a bit, but unfortunately been unable to find a proper solution either in docs, trial-and-error, or the mailing list. Honestly, I believe this might be a bug anyway, so I thought I would reach out here and see what you all think. I've also looked in past reports and wasn't able to find previous mentions of this, so I apologize if I missed something and this has been reported before. The main issue is that the Apache disk cache (specifically; I haven't tried other caching backends on this) will cache requests with the rewritten URL when said request was rewritten by mod_rewrite, rather than the originally-requested resource. This is mainly evident on CMS's that use so-called "pretty URL's" or "permalinks", where all requests are rewritten to "index.php" for processing. So, if I request, say: http://domain.com/page/1 This gets rewritten internally to http://domain.com/index.php and served normally. This results in the cache key showing not the original URI, but the rewritten one. Such as (when viewed with htcacheclean): http://domain.com/index.php? 942 20436 200 0....etc.... This means that, should I attempt to request, say, http://domain.com/page/2, this also gets rewritten to index.php, which causes the cache to erroneously think it has my request in the cache and serves that instead of properly realizing that the request is different. I would think that expected behaviour of the cache would be to store the request under the key as the originally-requested resource rather than whatever it may get rewritten to internally (redirects and such notwithstanding). Making the above instead appear as: http://domain.com/page/1? 942 20436 200 0....etc.... I hope this makes sense?
