I'll keep on your topic now. I thought you were trying to do something
related, but it doesn't look like that anymore.

I don't quite understand; but what is the difference to using URL's like

<a href="http://yourserver.net/thepage?param1=value1&param2=value2">

The params and values can be computed with javascript ( < a href="#"
onClick="location.href= computeURLwithParams();">link</a> ) where
computeURLwithParams() is a javascript function that returns a string
like

http://yourserver.net/thepage?param1=value1&param2=value2.

based on whatever you are trying to do.

I'm getting the impression you are trying to pass values to the server
in one request so that the response to the next request can take those
values into consideration. Can you not pass the values all in one go?
