I can't see something in chunk_filter deleting the Transfer-Encoding header if present and not chunked data...There is a dechunk filter, which as I understand was merged into either CORE or CORE_IN (if very rusty memory serves).
maybe i am in the wrong part of code. is there some dechunk_filter ?
Don't confuse chunking with dechunking, they do totally opposite things.
but i don't understand why mod_cache should store this header, because when it will serve the document from cache, i don't see why it should take care about how proxy received the data because it store all the data in the same brigade... cache->saved_brigade.This is because chunking is something that only a chunking/dechunking filter should worry about.
So if we delete the header each time we serve from cache, it will take more time than if we delete it before storing it in the cache_headers_out.
Unfortunately there seems to be a significant number of places in the code where parts of Apache are fiddling with things that should never be fiddled with in that part of Apache. Things like proxy fiddling with content_length, etc.
The solution to all of this is to ensure the code only touches what it should touch. This is what the filter stacks are for.
