To give you some background on the application, it is webmail using roundcube(php) and is doing these calls when users insert images/media from external sources in compose window (either via html editor or via the image/media insert buttons we provide). So, those are not really important for us and we don't want apache to wait for those responses forever. I see that the Timeout configured in our configs is 30 sec but as per doc[1], it seems it is the amount of time the server will wait for certain events before failing a request but in this case, apache is forking a child and it is waiting for an external call to complete.
I see a difference between this and when apache is serving a request and wondering if the same Timeout applies?
