Hi guys,

can anyone explain me how
isTokenValid(javax.servlet.http.HttpServletRequest request)
and
saveToken(javax.servlet.http.HttpServletRequest request)
works in struts.

Thanks,
kundan

When saveToken() is called, a hidden field will automatically be added to forms in your jsps (assuming you use html:form). The Struts servlet stores [in session] the most recent token.

isTokenValid() checks to see if the hidden variable submitted with the form matches the most recent one set through the saveToken method.
 
It is sorta covered in the JavaRanch Style Guide.
