I agree, here's how I solved the problem. I moved server specific
functionality to a static method of my "ServletContainer" class, whose
behavior is configurable at run-time via a properties file:
# Set this to true if your servletContainer interprets the root of the
# request URL as relative to docroot, rather than to context root
# should be true for tomcat, false for orion (as of 7/17/00)
# default is false
sendRedirectUsesDocroot=false
It then contains this method:
/**
* Redirect the client browser to the specified URL.
*
* Some servers do not handled relative paths the same. Some
* make the request relative to docroot, others the context root.
* This method is sensitive to the property
* <code>sendRedirectUsesDocroot</code>, which should be set to
* true or false.
*
* @param req the request
* @param res the response
* @param href the url to redirect to (before any conversion)
**/
static public void sendRedirect(HttpServletRequest req,
HttpServletResponse res, String href)
throws IOException {
if (ServletContainer.sendRedirectUsesDocroot() && href.startsWith("/"))
href = req.getContextPath() + href;
Debug.println("Redirecting to " + href);
res.sendRedirect(href);
}
All my code (taglibs, servlets, etc) that needs this functionality defers it
to this class.
