#684 RAW request removes port when there is "_" in hostname

[Srirama MK]

Hi, I have been observing a wierd issue. when i type endpoint as "https://hostname:123/Services" RAW request generates correctly as "POST https://hostname:123/Services/PASEntitlement_v1 HTTP/1.1"
but when i type "https://host_name:123/Services/PASEntitlement_v1" RAW request removes port "POST https://host_name/Services/PASEntitlement_v1 HTTP/1.1" .
though this is very silly, but i am unable to post.
Please help asap.
Thanks.
