My application implements the javax.servlet.Filter interface. But I've got a weird case. One of my ActionBean instances is returning response to one jsp, this jsp contains an <iframe> tag. in this tag, src attribute has same request uri as this jsp but with change in param values. But the uri inside <iframe> is not being requested.
I've tried to remove Filter from my application. Then it works fine. So what should I do while using Filter interface ?
Issue solved...
The thing I need to take care about is I can not Redirect the request. I've to forward it. And it was out of my mind.
Filter can not harm your request if you use it wisely.
