provider that caching is complete, giving the provider the opportunity

to commit temporary files permanently to the cache in an atomic

fashion. Replace the inconsistent use of error cleanups with a formal

set of pool cleanups attached to a subpool, which is destroyed on error.

[Graham Leggett]

*) mod_cache: Change the signature of the store_body() provider function

within the mod_cache provider interface to support an "in" brigade

and an "out" brigade instead of just a single input brigade. This

gives a cache provider the option to consume only part of the brigade

passed to it, rather than the whole brigade as was required before.

This fixes an out of memory and a request timeout condition that would

occur when the original document was a large file. Introduce

CacheReadSize and CacheReadTime directives to mod_disk_cache to control

the amount of data to attempt to cache at a time. [Graham Leggett]
