Hey All,

I have some classes that I recently built for a website which uses the
HttpWebRequest & HttpWebResponse objects from the System.Net namespace.
Basically, the classes rap submitted data up, connect to external websites
on external servers and post / remove the data from these other sites.

It works fine locally but when uploaded to the BCentral production server,
the outgoing requests get shutdown.

Apparently, for the System.Net name space, you cannot specify the port. The
outgoing port will be dynamic random. It will be the client port and not the
service port. The port range can be 1024 and above. It is by design and
there is no way you can specify the client port.

Now, as for BCentral, they do allow outbound connections but only on the
"default" ports such at 80 for http, etc. Every other non-essential port
is locked down and they don't open up other ports because of security
concerns.

Can someone please advise?

Thanks,

TC

Hey Bruce,

I'm going to post some material inline herein. Let's just assume that all
constant strings, values, viewstate, etc. work.

I think if I paste in the material with the actual calls, it might mean
something to you.

Thanks,

TC
