Attachments: Patch to avoid sending port number in URL when port is 80

Patch to avoid sending port number in URL when port is 80

Papyon 0.4.6 sends out requests to MSN's server that cause the server to return a 400 HTTP response ("Bad Request").
When such responses are received, telepathy-butterfly (through it's use of papyon) suffers from a huge memory leak. (about 200MB per hour on average)

Detailes:
In http://support.microsoft.com/kb/826437 you can see that the .Net framework 1.1 does not accept requests that contains ":" in the host name AND "&" in the URL because of a bug.
Papyon sends requests to port 80 to a URL of the form: http://65.54.48.32:80/gateway/gateway.dll?Action=poll&SessionID=962514443.0
The MSN server then responds to these responses with a '400 Bad Request' response.
These responses also result in a huge memory leak.

Workaround:
Since it is not necessary to send the port number with the URL when the port number is 80, I created a patch that avoids sending it in this case. This helps to avoid the 400 responses as well as the memory leak.
This attached patch relates to the papyon/gnet/protocol directory

Further details:
OS - Ubuntu 10.04 64 bit with all latest updates.

So that patch fixes things for you ?! Weird.. what happens if the port is not 80 ? It accepts the extra ":" then ?

Do you have more info about the memory leak ? Where exactly does the response is leaked ? Thanks.
