your data would be something, similiar to:
var %data = username=Coolkill&password=testing123&ect
so, then you use $len(%data) for the content-length and where your data is, use %data.
To know what to send, view the source (as shown above) and all the data between the <FORM> and </FORM> html tags, such as editboxes, hidden tags will all be in your data, i.e.
<FORM>
<input type="hidden" name="page" value="loginpage">
<input type="text" name="username">
<input type="password" name="password">
</FORM>
would result in, data being: page=loginpage&username=[color:red]username&password=password[/color]
Where the red would be replaced by the users input obviously, if you get stuck paste the url for the page your trying to POST for.
