problem: reading values from ServletRequst in Filter

problem: reading values from ServletRequst in Filter

problem: reading values from ServletRequst in Filter

I am trying to intercept all request info (GET and POST method) coming from a user.

So I have a filter that captures some basic info (request method and uri) from request. But whenever I read parameters contained in http request for "POST" method, I can't figure out how to repost parameters to request. I think that after I read parameters from request in filter, parameters aren't available in http servlet. I think that I have to repost parameters to request after i read it.

does anybody know how to do it?

RE: problem: reading values from ServletRequst in Filter

I thought about using session. but the filter is just a simple interceptor for a web application. I don't want to change the coding of the web app because of this filter.

any better idea?

RE: problem: reading values from ServletRequst in Filter


The POST requests are composed by the browser, so you can not influence it directly with server-side script. You can pass those previously received parameters in a form's hidden inputs than each link will submit() that form using JavaScript on onclick event. ( Although some people use such solutions, I consider it stupid. )

I do not understand why do you consider implementing session bigger change then playing with parameters.

And why cannot just redirect the request?
