I'm happily using mod_perl to serve content stored in a mysql database. Basically, the content does not change really often, and it maybe important (BLOB containing images). It seems that handling cache-related stuff would be a big win. For example, the If-Modified-Since: (sp?) header and that kind of stuff. Question: - does apache/modperl handle some of that stuff? - is it useful to handle HEAD requests specially Next, what do I have to do to enable persistent connections on the server (it's images in a database so that will be actually used!), do I just need to provide a Content-Length header, and apache/modperl will automagically reuse the current connection?
