Sorry, reverse proxy is not a proxy -- it is a gateway.
Sure it is. but that's semantics and any further discussion of that would be futile.
You are right that it won't make a difference in the gateway case, though from a software design perspective, pipe-and-filter architectures depend on sending errors down the pipe so that each filter can handle the error. Having the filter set a global variable that is normally private to the client connection, just for the sake of obtaining the side-effect desired specifically for HTTP and mod_cache, is, well, unclean.
No, we are aborting the entire response in the proxy handler. Other modules (see mod_dav) already do something similar.
If we to handle this via an "error" bucket, this needs to be well advertised, as several things now just check r->connection->aborted (mod_proxy_http for one).
As is, the current "feature" has halted and reversed my roll-out of 2.2. -- Brian Akins Lead Systems Engineer CNN Internet Technologies
