UseDefaultWebProxy = true not working on send port to call web service.

Question

Hi
I have a local http proxy and have set this up in IE - which is working fine (confirmed through proxy log). I am testing a wcf basicHttpBinding to an asmx web service. Setting the useDefaultWebProxy = true does not trigger the send port to use the proxy
(I can confirm this via the proxy logs). However setting this property to false and explicity setting the proxy using the proxyAddress binding property will cause the send port to use the proxy to send the request.
My understanding was that setting the useDefaultWebProxy = true causes the send port to use the
auto-configured HTTP proxy of the system (which I set up in IE).
Furthermore removing
the proxy address from the proxyAddress property and changing back to useDefaultWebProxy = true causes the send port to error with the error along the lines of "You cannot specify an explicit Proxy Address as well as UseDefaultWebProxy=true" even
though the proxyAddress property is now cleared. Changing back to useDefaultWebProxy = false causes a different error "System.InvalidOperationException: This operation is not supported
for a relative URI"
The only way to fix this is to re-import the bindings

Hi,
Are you sure the proxy is configured (using IE) for the user running the host instance? (Especially on non development machines) this is not by default the same user as the currently logged in user.
