Referrer page
I have implemented a search using servlets and jsp. This search starts with a form where the user writes the search criteria. When the user submits the form a doGet method from a ServletQry answers and sends back a list of results.
As this list may be too long I have added two links 'Next' and 'Previous' that uses url rewritting to pass all the parameters plus the amount of results showed.
This search must be used in more than one place of the intranet site, so I save the referrer page (request.getHeader("referer") ) as a hidden field of the form, so it is possible to go back to the page that initiated the search.
The problem is when I pass the referrer page as a parameter in the 'Next' and 'Previous' links (for example the url in the links 'Next' and 'Previous' is:
....servletQry?name=John&doc=&next=10&referrer=http://sys:8080/servletA?op=1&id=200)
When I inspect the request.getParameterMap() object, the referrer is disarmed. I cannot find 'referrer' as a parameter name, but I find
http://sys:8080/servletA?op as parameter name
and
1 as the value of this parameter
and the rest of the parameters, in this case id=2 is as other parameter but the problem is that I need it as parameter of servletA and not of servletQry
Please I need any idea of how to solve this or why is this happening.
Thank you in advance
