           Summary: mod_proxy keeps alive connections that should be broken
           Product: Apache httpd-2
           Version: 2.2.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: claire.chauvet@neolane.net


I use an Apache as a reverse proxy to send request to an other Apache Web server.
When I close the connection (whith a clean socket shutdown or not), the reverse
proxy does not break the connection with the target web server.
It's really a problem when a web application use the broken connection to detect
a job cancellation. And i think this could be used for denial of service attacks.

I have posted an issue to APR team which is related to this one. 
http://issues.apache.org/bugzilla/show_bug.cgi?id=40348

I would actually expect mod_proxy to keep as much as smax connections opened 
but it will not: under normal load situation, pool to backend web server 
remain at the size of the maximum used.
=> always closing connections would lead to poor performance 

For http connections, a quick workaround is to disabled keepalive connections 
on the backend servers: better is to configure keepalive connections with 
reasonable timeout.

------- Additional Comments From nick@webthing.com  2007-09-08 15:37 -------
Connection is defined in RFC2616 as a hop-by-hop header.  Thus the transaction
between client and proxy is independent of that between proxy and backend.

Reclassifying this as an enhancement request, to be able to control behaviour.
