Make a link pass extra information to a JSP

I want to do something like this: 

<a href="myJSPFile" onClick="request.setAttribute("special case")"> click here </a>

Any way to achieve this?

You could put all information in a session which then would be better if the browser closes unexpectedly. Some sample code:
In the first page when the user clicks. 

session.setAttribute("nameOfAttribute", informationForAttribute);

To retrieve the information: 

session.getAttribute("nameOfAttribute")

This would then mean you can have a cleaner URL as you don't have to place query strings in the URL.

Here is a useful link on sessions.

Use the querystring.

<a href="myJSPFile?specialCase=imSpecial">click here</a>

Then read it with

request.getParameter("specialCase");
