Check if port 54007 is free before running web-server about phpdesktop HOT 13 CLOSED

I've just run multiple instances of phpdesktop and seems that
there is no problem running multiple php web-servers on the
same port. Why is that possible?

Mongoose seems to be fine when running multiple instances of an
application with each instance starting web-server on the same port.

Check also if "remote-debugging-port" is free. If not, generate some random 
port for that too.

When launching a second application that has the same listening port set, then 
the content from the first application that started a webserver on that port, 
will be served. So this is some serious issue. If there are two different 
applications and we display application 1 content in application 2, then this 
is really bad.

Each instance of the same application should run on a different port, otherwise 
the --cgi-environment argument used to launch a second application instance, 
will not take effect as it is the first webserver that will be serving content.

After a minor modification to mongoose sources, it now accepts port "0", 
thereby OS assigns a random free port. Now I need a way to get know the port 
that was assigned. Created a topic about that on mongoose-users group:

Fixed in revision 8091beb8d108. When port is set to 0 in settings.json, OS will 
assign a random free port.

Chrome 31.4 and MSIE 1.12 released.

Project will move to Github. Find this issue at the new address (soon):
