check_http: add check for virtual port usage

[odenbach]

Hi,

I just added a test for virtual port usage:

./check_http -H 127.0.0.1 -p 50637 -u /virtual_port

will fail, while

./check_http -H 127.0.0.1:80 -p 50637 -u /virtual_port

will succeed.

Any Comments?

Thanks,

Christopher

Hi @odenbach,

thanks for sharing. A small side note:

Please do not make changes to the master branch of your fork but create a own branch for every fix/feature/contribution. Otherwise you/we/all will end up into a mess.

Thanks and cheers, Jan.

Also please do not change existing tests, like the "run_common_tests" unless neccessary. I think its better to add new tests along the existing ones.
Also i added some tests last week with 9e02d0c. Does this PR add different checks?
