Greetings All,
I would like to pose another related question on servlet alias mappings
and paths.
How should I map servlet such that it is invoked only for files ending
.html in certain folder (and subfolders).
For example /foofolder/bar.html invokes the servlet but
/foofolder/bar.gif is handled by the default file servlet. (I don't
want to deal with any multimedia objects but I do want to modify
outgoing html.)
It seems that mappings want to be either folder rules or file ending
rules but not a combination???
Thanks,
