// GET /ua-echo -> echoes the number of Values and the joined value seen on

// the incoming User-Agent header back as x-ua-count/x-ua-echo.

//

// h1OffloadThreads > 0 (matching proxyplus's own HttpProxyController) runs every request

// through the H1 offload/detach-reattach path (see httpd.h's shouldOffloadH1Dispatch doc

// comment) instead of the fully-synchronous default -- this is what testKeepAliveDoesNot

// AccumulateHeaders below actually needs to exercise, since the header-accumulation bug this

// whole file guards against turned out to be specific to that path (the synchronous path

// already resets header state via HttpEvent::ResponseEvent(); the offloaded path's own

// cleanup never reaches that call, since it deliberately returns with a null csock so

// IoEventHandler stops touching the connection immediately -- see _dispatchH1Request's doc

// comment in httpd.h).
