2501 *) mod_cache: Add a discrete commit_entity() provider function within the
2502 mod_cache provider interface which is called to indicate to the
2503 provider that caching is complete, giving the provider the opportunity
2504 to commit temporary files permanently to the cache in an atomic
2505 fashion. Replace the inconsistent use of error cleanups with a formal
2506 set of pool cleanups attached to a subpool, which is destroyed on error.
2509 *) mod_cache: Change the signature of the store_body() provider function
2510 within the mod_cache provider interface to support an "in" brigade
2511 and an "out" brigade instead of just a single input brigade. This
2512 gives a cache provider the option to consume only part of the brigade
2513 passed to it, rather than the whole brigade as was required before.
2514 This fixes an out of memory and a request timeout condition that would
2515 occur when the original document was a large file. Introduce
2516 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
2517 the amount of data to attempt to cache at a time. [Graham Leggett]

2527 to return cached content at all, and respect a "Cache-Control:

2529 behave like "max-age=0". [Graham Leggett]
