http test

Hi !

Can somebody tell me  how the http-check work ?

.. i see nothing like "curl, etc." in the source

xymonnet/httptest.c

The reason ist, that after a normal http-check on a windows-server,
the application craches .. .i can't believe that the xymon-http-test 
should be the reason, but i've to tell how does xymon test a webside ...

thank & cheers
