Connection aborted with istSOS behind a proxy

If istSOS is deployed behind a proxy, and some big amount of data is sent or requested.. An execption can be thrown because of the timeout between the proxy and the istSOS server.

This can be corrected configuring Apache with a long timeout interval:

ProxyPass /istsos http://x.x.x.x/istsos keepalive=On timeout=480
ProxyPassReverse /istsos http://x.x.x.x/istsos

It would be nice to catch this exception and notify the user about the wrong server conffiguration.
