Hi, I 'm currently deploying a WFS Server with C# mapscripts. The
Request issued by openlayers is xml-encoded post request.<br>
When I
tried to use "loadparam", it exited abnormally. So I had to parse
parameter by myself. So my question is: do I have to parse the
xml-encoded post request manually?<br>
is there a function I can use to
parse the post request?<br>
<br>
