Poster is the second Firefox extension that I mentioned in the last posting. It can be used for invoking any of the requests in the SmartCloud Enterprise (SCE) REST API, including GET, POST, PUT, and DELETE. To install it go to Tools | Add-Ons | Get Add-Ons and search for 'poster.' Install it and restart Firefox. For more details on Poster, see the project web page at http://code.google.com/p/poster-extension/.
You should now see a Poster menu item under the Firefox Tools menu. Click on that to bring up the Poster REST request dialog. This is shown below.

Then click on the GET button. You will be prompted for your user name and password. You should see a response dialog like shown below.
