Xojo.Net.HTTPSocket and Timeouts

Last year I moved a client app from old HTTPSocket to Xojo.Net.HTTPSocket to get HTTP 1.1 support and proxy handling. Oh, well, I should have gone the plugin way as now client asks for a timeout. Some requests take longer than 2 minutes on server to provide responds and we get timeout errors in the app.
Before we switch everything to CURL, I checked for an easier way and looked into patching the Xojo class to use new timeout. Looking on a stack trace on how it works, you see this:
4 Window1.Window1.Event_Open%%oAs you see the Xojo.Net.HTTPSocket class is implemented in C++ code and uses NSURLConnection class on Mac for the job. So I created a new NSURLConnectionFilterMBS class, which allows you to filter the call to initWithRequest:delegate:startImmediately: function. All calls to initWithRequest:delegate:startImmediately: are intercepted, our event FilterConnection event is triggered and you can modify the request, before the connection is created. So for Mac at least we can fix the timeout issue.(in test.debug) + 574
4 Xojo.Net.HTTPSocket.Send%%oyy (in test.debug) + 63
4 HTTPSocket_Send (in XojoFramework) + 83
4 HTTPSocketImpNS::Send(Text const&, Text const&) (in XojoFramework) + 312
4 HTTPSocketImpNS::StartConnection(Text const&, Text const&) (in XojoFramework) + 478
4 -[NSURLConnection initWithRequest:delegate:startImmediately:] (in CFNetwork) + 43
4 -[NSURLConnection(Private) _initWithRequest:delegate:usesCache:maxContentLength:startImmediately:connectionProperties:] (in CFNetwork) + 190
4 -[NSURLConnectionInternalConnection initWithInfo:] (in CFNetwork) + 1301
Coming soon in next prerelease for MBS Xojo Plugins 18.2.
