Bad file size in disk cache for large css files





------- Additional Comments From ruediger.pluem@vodafone.com  2004-08-24 08:53 -------
I guess my problem is the same. I use mod_disk_cache to cache static files
delivered by Tomcat via
mod_jk. Unfortunately you did not write if you are caching local files or remote
files (delivered
by mod_jk, mod_proxy or something similar).

I noticed that when you abort the download of a file which should be cached and
whos origin is
on a remote server, the partly downloaded file gets cached.
The second request for this file only delivers the partly cached file and thus
leads to the problems
described by you. In my case the problem showed up by incomplete jpg pictures.

The reason for this behaviour can be found in mod_disk_cache. mod_disk_cache
does not notice
that a request has been aborted. I wrote a small patch (against 2.0.50) that
drops the partly cached file
if the connection has been aborted. 
Unfortunately the CacheForceCompletion of mod_cache is not implemented right now
such that nearly
completely downloaded files get lost for the cache. But this is better than
delivering only
parts of the files in the following requests.
