Is it possible to continue to run the main infinite loop along with the server ?

Hi, first of all this is really a neat piece of work you have done. I have a question and if it can be addressed, it would be a perfect combination.

When we run your webserver, it interrupts the main infinite loop of mbed.

If we would like to run things like logic control, data logging or similar stuff that is not possible once the webserver starts the loop.

Can this be modified ?

Thank you,

Orhan Dengiz

Please call Httpd::loopTask() instead of Httpd::loop();
