I'd like to thank Bruce Johnson for
supplying supplying information about the setup of a proxy
for web service calls. To specify a proxy in the config file, add the following
in the configuration section:
<system.net>
<defaultProxy>
<proxy
usesystemdefault="false"
proxyaddress = "http://proxyserver:80"
bypassonlocal = "true"/>
</defaultProxy>
</system.net>
