The URL http://myserver/Construction/ (with trailing slash) yields the same
results as http://myserver/Construction (without trailing slash).
I think I may have solved the problem. I didn't write this webapp, but have
inherited it so I'm still learning it's inner workings.
The controller servlet is using three
rd = req.getRequestDispatcher("something.jsp");
rd.include(req,resp);
blocks (with essentially header, main content, and footer .jsp files) to
assemble the final output page. Initially there was no req.setContentType() at
all. Once I added req.setContentType("text/html") it appears to have resolved
the problem.
w00t.
I've used rd.forward() and don't think I ever had to use setContentType(), but
have never used rd.include() in my own webapps. I guess since include() adds
only a portion of a page, you have to treat the whole deal more like a servlet
and explicitly set the content-type.
Thanks for the help.
