Subject: http: expose reused connection counter in PSGI env
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1a0e93016f6649340844c9d3a11cf2435ab6ca19;p=thirdparty%2Fpublic-inbox.git

http: expose reused connection counter in PSGI env

`$env->{pi-httpd.request_nr}' is now accessible via the PSGI
env for middlewares to use to identify reused connections.
This can be useful for middlewares to implement rules for
identifying and rejecting/allowing certain clients (e.g.
aggressive bots).
