Kommander HTTPform plugin enables you to use HTTP post and get. This can be extremely useful. it can retrieve a web page or the underlying markup. What it's particularly useful for is creating a web form integrated with your application. I use this to synchronize databases by putting PHP files in an admin area and exchanging message keys.
Note that this version requires version 1.3 of Kommander released with kdewebdev 3.5.9 Earlier versions are avaliable in the download section of our web site, but they do not include the new fuctionality listed below.
