I am not sure if it's me who's doing it wrong or if there is an error.
When I hit HTTP Send Test / Send Static Data it shows "Sending..." and will stay like this until I hit cancel.
I also get the following error

WARN  2013-10-21 12:20:07,223 (com.serotonin.m2m2.web.dwr.MiscDwr.jsError:176) - Javascript error
   Description: TypeError: PublisherEditDwr.httpSenderTest is not a function
   Line: 567
   Browser name: Firefox
   Browser version: 23
   osName: Windows

Apart from this, what I am trying to do is to post some info via HTTP GET to a Cai WebControl board.

The URL would be

But I am using a password, so maybe


Or using static HTTP headers. That's what I am trying to figure out.

Under Static Headers I entered

Authorization=Basic YWRtaW46cGFzc3dvcmQ=

(The string is base64 encode of "admin:password")

Is what I am doing about right?

Eventually what I am trying to do is update a value as above on a certain event (ie. HTTP Retriefer receives an alarm).
