Filters
Greetings.
I have a questions regarding Filter servlets. If a request is made for a
non-existent/non *.jsp or servlet URI - will the Filter be instantiated?
Reason I ask is because I want to interect old bookmarked requests for an
old site - which has been migrated to a new tomcat based JSP site - however
the old site was ASP based.
Many users of the old site would have bookmarked something like:
/index.asp?PageID=16 or something similar - and I am hoping to be able to
intercept that - using a Filter seemed a logical choice - and send back a
redirect to the new URL /some.jsp for those requests.
Thanks in advance,
Carl

hi,
Sure, you can map your filter on to /* or something like that. That way you
can intercept any URL you like and either rewrite, or redirect.
It doesn't matter if your URL reads /something/something/default.asp or not,
if you know how to handle that url from your filter (usually done by reading
config from file or database). If you are using mod_jk then you might have
to change your mapping in to tomcat.
I've been implementing this by using filters for a long time, never had
problems with it.
hope it helps

Carl,
I'm quite new to this but I'd guess that the Filter is
instantiated at start-up by Tomcat. You might direct
your new requests, plus the old requests for the asp
pages, to Tomcat, using say Apache. Using a filter you
could intercept *.asp and then forward/redirect to the
new resource.
