Description Ben RUBSON 2017-10-15 16:08:12 UTC 
Hello,

I found that ProxyPass ping option does not work with HTTPS remote servers.

Test case to reproduce the issue :

Apache remote server, with prefork MPM :
StartServers      1
MinSpareServers   1
MaxSpareServers   1
MaxRequestWorkers 1

Frontend server :
ProxyPass "/" "https://<remote_server>/" ping=2

Open a first connection to the server which takes time to proceed.
Open a second connection, it should return after 2 seconds, however it does not and stalls up to timeout (ProxyTimeout).

Move the remote server to HTTP (and ProxyPass to http://), the above test will then succeed.

Any reason why it behaves like this ?

Many thanks !

Ben
