Specfic Question Regarding CI Caching

[eluser]nmweb[/eluser]
The md5 hash of the URI is indeed used as the cache key. This also leads to the issue that fabricated urls (leading to 404's) also are cached. Say example.com/article/view/1/title-of-the article brings you to article with id=1. With caching enabled example.com/article/view/1/another-title, article/09809 etc. ad infinitum, will also trigger caching. I believe the cache is stored in one dir so if an insane amount of urls are cached this might lead to slowdowns or the gradual filling of the harddisk. Both of which are undesirable. I believe this issue is not yet resolved.
