1528283 - Consider on-demand data coalescing by nsHttpTransaction

Status: NEW

(Core :: Networking: HTTP, enhancement, P3)

Description

[Honza Bambas (:mayhemer)]

Some consumers, like js and css loaders, don't do at the moment incremental parsing and only collect the data to be parsed as a final blob in onstoprequest. Some servers are sending data in very small chunks (kB) possibly leading to overhead from messaging chains each chunk invokes.

The idea is to have an API on nsIHttpChannel(Internal) to call before AsyncOpen taking number of bytes to coalesce by. Data would then be buffered in lower network levels, flushed on overreaching the limit or when onstoprequest fires.

This is experimental only.
