Hi all, I am using the latest stable version of Tomcat Embedded. I have a question regarding how redirect works for a servlet. My servlet mapping name is "RexaRetrieval". The basic problem I was having is that when I send a POST request, the HttpServletRequest always says it is a GET. If the URL I put in is: "http://localhost:8081/RexaRetrieval" This causes a redirect to a GET request. If the URL is: "http://localhost:8081/RexaRetrieval/" This works. The only difference is the trailing '/' character. Resin does not have this problem. When I deploy the same war, both POST requests work. The relevant source code is in org.apache.tomcat.util.http.mapper.Mapper line 641: 1 boolean noServletPath = false; 2 3 int length = context.name.length(); 4 if (length != (pathEnd - pathOffset)) { 5 servletPath = pathOffset + length; 6 } else { 7 noServletPath = true; 8 path.append('/'); 9 pathOffset = path.getOffset(); 10 pathEnd = path.getEnd(); 11 servletPath = pathOffset+length; 12 } Note the !=. This means if a trailing forward slash is missing, "noServletPath" is true. The in Mapper line 688: 1 if(mappingData.wrapper == null && noServletPath) { 2 // The path is empty, redirect to "/" 3 mappingData.redirectPath.setChars 4 (path.getBuffer(), pathOffset, pathEnd); 5 path.setEnd(pathEnd - 1); 6 return; 7 } Another related question: how is this redirect suposed to work? The original method was POST. Does it always redirect to GET when there is a servlet path? What if I were to post to a URL like "http://localhost:8081/RexaRetrieval/foo". I am guessing the correct action here would be that this redirects to a GET because posting to such a URL doesn't make sense. Thanks, Rich |
