Getting back to the previous jsp

[Randahl Fink Isaksen]

On one of my JSPs I would like to have a link to the previous page (a "back"
button), but then i need to output

<a href = "<%=theLinkToThePreviousPage%>"/>

Does any one know how I can replace "theLinkToThePreviousPage" with a Java
expression which retrieves the correct url?

Thought about letting the caller transfer the link as a parameter to the
JSP, but I would like to avoid this, if possible.


Thanks
