Ok, for a form action, I want to redirect a page to itself, passing parameters. The problem is that the name of the page will be dynamic or generic where I wont be able to tell wehta the name is.
For example a page called test.jsp
has a line that is liek the following...
<form action="">
The action will return to this same page. That is fine but I want to be able to pass pararameters like
<form action="test.jsp?name=Anthony">

I'd be wary about trying to pass data by including it in the form action attribute, since from experience its support is browser dependant: Some keep it and some just ignore it.
You are better off including it as a hidden field.
Dave.
 
Don't get me started about those stupid light bulbs.
