[users@httpd] Which proxy modules are required for proxying Websocket connections?

All,

If I want to allow HTTP connections to upgrade to WebSocket, which
mod_proxy modules do I need to enable and configure?

More specifically, do I need to enable+configure both mod_proxy_http
AND mod_proxy_wstunnel, or only mod_proxy_wstunnel?


  # Do I need these?
  BalancerMember http://node1/
  BalancerMember http://node2/

  # Or only these?
  BalancerMember ws://node1/
  BalancerMember ws://node2/

  # Or both?


ProxyPass /my-app/ balancer://my/app/

Is the answer any different if I don't expect all connections to be
upgraded from HTTP -> Websocket?

Thanks!

[users@httpd] AH02429: Response header name 'application/x-www-form-urlencoded'

[Wendell Hatcher]

Hi I am getting the following error we were not getting it in apache 2.4.17
but we are getting in our upgraded version 2.4.39.
AH02429: Response header name 'application/x-www-form-urlencoded' contains
invalid characters, aborting request, referer:
https://s1-integration.ariba.com/Buyer/Main/ad/contentPunchin/OCIPunchinDirectAction?sap-client=100&;...

my question are the items the upgraded version of apache will reject is
there a list such as spaces etc... that it no longer accepts

[users@httpd] File structure for nearly identical sites

[Darryl Philip Baker]

I am getting a set of over 50 sites moved over to my server from elsewhere and 
the content manager want to duplicate each of these in a dev subdomain. An 
example eatatjoes.example.com and eatatjoes.dev.example.com. I am thinking that 
I can include the same configuration file twice if I replace the “dev.” with a 
macro. The first time in include the file the macro has the value of “.” And 
the second time the value of the macro is “dev.” I would do something similar 
for the document directory.

Is there a way of keeping some directives from being in the live configuration 
for just the second time I include the file?

In my case there are likely to be redirects as they test a site prior to a 
relaunch. They like to keep bookmarks working even after restructuring a site.

[users@httpd] Reducing 503 errors

[Mahmood Naderan]

Hello
With the following MPM settings

    ServerLimit   500
    StartServers   5
    MinSpareServers   5
    MaxSpareServers  10
    MaxRequestWorkers 500
    MaxConnectionsPerChild   0




I would like to know how can I reduce the occurrence of 503 (service 
unavailable) error? Should I increase ServerLimit only? Or MaxRequestWorkers? 
Or increasing one and decreasing the other?


Regards,
Mahmood
