Port 80 / Corporate firewall

[James Weatherall]

Jason,

Are you saying that your work "firewall" only allows outgoing connections on
port 80?  Are you sure that the work firewall is not in fact an HTTP
proxy/firewall combination (i.e. something that only allows actually HTTP
traffic through)?

Regards,
