Invoke-WebRequest : This operation is not supported for a relative URI.

With a lot of help from experts the following code is working fine:-
$postParams = "username=me&moredata=qwerty66"
$test = Invoke-WebRequest -Uri http://localhost/TestForm.php -Method POST -Body $postParams -Proxy ''

write-host $test

Open in new window

However if I put an external domain in:-
$postParams = "username=me&moredata=qwerty66"
$test = Invoke-WebRequest -Uri http://test.tonycross.me.uk/testForm.php -Method POST -Body $postParams -Proxy ''

write-host $test

Open in new window

I get:-

Invoke-WebRequest : This operation is not supported for a relative URI.
At D:\Users\TCross\Desktop\Post Data - Invoke.ps1:5 char:9
+ $test = Invoke-WebRequest -Uri "http://test.tonycross.me.uk/testForm.php" -Metho ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Invoke-WebRequest], InvalidOperationException
    + FullyQualifiedErrorId : System.InvalidOperationException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

What its supposed to do is just post some data to a webform and get a response from the server.

Any ideas what Im doing wrong?

Thank you

This really isn't a command I've used before so the help I can provide is probably limited, but since no one else had replied yet...

The command worked for me if I removed the -proxy parameter.  So I'm thinking the problem must be there.
