The redirect method should not add any params on the end of the url unless you
are adding them to it. Do you hard code the url or are you passing a variable.
Try hard coding the url to the servlet like
redirect("http://www.test.com/servlet/FormHandler");
This will redirect the browser to the specified servlet and will not add any
params to the end unless you add them yourself. I have plenty of Servlets using
this method to post to themselves and if any of the params where passed they
would not for because the else statement would not be executed but the work
perfectly. I will use this disclaimer though. I am using Jrun with Netscape
and IIS and it works perfectly. I would also need information about your code,
the code that you are using to refresh, detect the parameters on the query
string, web server, servlet engine, etc. to be of further assistance

Hi,
I tried the send.Redirect method. It does redirect the browser to the
original url but the parameters last set of parameters are still passed on a
refresh. The reason I use refresh is that the data updates are not
instantaneous. When the user submits the data, a new page is displayed but
the new data will not be displayed. The process the new data goes through
may take up to 30 minutes. If the user wishes to wait for the new data to
be displayed, they can simply hit refresh every few minutes to see if the
updates have been completed or they can leave the web site and return later
to see the new data displayed. Whenever the screen is refreshed, even
though the redirect hides the params at the end of the url, they are still
re-submitted. Any ideas?
