RE: Multiple browsers and servlets

I think it's browser's fault. Has happened to me under
the similar circumstances, developing servlet for
conversion into PDF using
HttpServletResponse.getOutputStream(). Worked fine on
my IE6.0/Win98 and called servlet twice on
IE5.5/Win95. No string ".pdf" in input parms.

Solution:
uncless you can afford to by Microsoft and make them
correct it, switching from GET to POST when invoking a
servlet does a job.

There can be another reason. If you use the Java
script to submit a request, there may be a situation
where form is submitted twice, once from script, the
other time from action attribute on the form itself.
Solution: Clear the action attribute.
