My java program needs to rewrite urls in html (just in time). I am looking for the right tool and wonder if antlr is doing the job for me?
For example:

I've used tuckey's UrlRewriteFilter in small projects, but I'm hesitant to use such a thing in a production environment that could touch tens of thousands of paying customers (it feels kludge-y). ... |
I'm porting an IIS asapi filter over to linux/apache, and am wondering what the best path to take it. On IIS, this isapi filter intercepts the request, performs a database lookup ... |
I believe URLRewriting is used when the app server can't use cookies to store session data. The URL is rewritten to include a hash, which when read from the server at the time of the next request, will alert the server to find the correct session on the server. http:\\www.myCompany.com/servlet/AServlet would be rewritten as something like: http:\\www.myCompany.com/servlet/AServlet?Session=4JwI34QW83f6R (backslashes used to hopefully ... |
Hi We track sessions 2 ways. 1. Cookies 2. URL Rewriting. URL Rewriting is a method used to track sessions when the browser being used by the client does not support cookies.In this process, all links and redirections during the client session must be encoded to include session ID as part of the URL. Hope this helps Regards Suneel [This message ... |
Hi, I am in a fix right now. can anybody tell me from their experience if JSWDK-1.0 supports url rewriting using encodeURL if clint has disabled cookies. I tried useing encodeURL before passing out any links but still the links remains same without any session ID appended to it? If there is any other approach whcih I can take. Please help. ... |
Since we dont know whether our application is going to be accessed by a client that supports cookies, or whether the user has cookies turned off or not... why would it ever be sensible to use session tracking and/or cookes for client state information in an e-commerce app. Does it not follow that URL Re-writing should always be used??? Herbert. |

I use the following jsp to test url rewriting. I set my ie browser privacy to block all cookies and open a new browser. After I run this jsp, I get "from cookie" on the page. Why I can't get "from url"? I can't see session id after url. I need help. Thanks. ... |

HttpSession session = request.getSession(); if(session.isNew()) { // welcome guest and ask for name } else { String name = session.getAttribute("name"); // welcome *name* } } I hope the above code is right example of keeping track of sessions if cookies are enabled at client... I am not clear with URL rewriting, how we use it? Could any body please give little ... |

Hi Folks, My knowledge on this area is very poor and i am confused as well.. Simply response.encodeURL("/blahblah.jsp"); is fine.... The confusion comes here.. We as the developers don't know whether the client supports cookies or not... So dont love to take chances... The option is this.. Devise a way to check whether the cookies are enabled on the client's front.. ... |
Hi All, I have a servlet that can return data in multiple output formats including pdf, excel, html. Generating the files and setting the content works fine, but I'd like to rewrite the request URL (if possible) for a more standard output. For example, if the user requests "print.jsp", I would like the URL rewritten to "print.pdf" for PDF and "print.xls" ... |
Hi Priya 1. As HTTP protocol is stateless, so server has to use different technique to maintain conversational state between server and user. This conversational state is called "Session". There are two techniques which may be used by server to maintain session. a. Cookie b. URL rewriting In URL rewriting sever append session information in each URL send in the output ... |
1) URLEncoding may need to be activated on the server. I know in WebSphere it is a server setting. The same may be true for Tomcat 2) Some servers "know" that cookies are active and will not append the jSessionID to the URL (don't ask me how they know). Turn off cookie and ss if the URL is appended |

URL-rewriting is a way of maintaining a session between an HTTP client and a servlet container which does not use cookies. Rather than exchange a session ID in a cookie, the servlet container includes it in the hyperlink URLs it generates for servlets and JSP. my doubt is when a servlet returns with URL rewritten. where is the information stored if ... |
Hi, I have a scenario wherein I want to force the encoding of a URL so that response.encodeURL() appends the sessionid to it. At the moment this API is not appending the sessionid which I guess is because session is being tracked by cookies , in which case the API method does not necessarily appends the sessionid. Is there anyway I ... |

I'm doing the HFJSP tutorial and trying to understand url rewriting. Since it's already done, I'm simply making modifications to the beer example to gain an understanding of this. In my servlet code, after getting a list of my favorite beers, I use the 3rd version of the app that uses the RequestDispatcher, in which I attempted to encode the url. ... |
You will require a DNS level API that is capable of adding sub domains. You cannot achieve this redirecting the URL since the DNS name for T.xyz.com will not resolve unless you add the appropriate records in DNS. You will need a CNAME if the subdomain points to the same IP and a 'A record' if the IP address is different ... |
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { String requestUri = new UrlPathHelper().getRequestUri((HttpServletRequest) request); //abs/store/1234 String sevletPath = new UrlPathHelper().getServletPath((HttpServletRequest) request); //store String contextPath = new UrlPathHelper().getContextPath((HttpServletRequest) request);// abs if(requestUri.endsWith("store.do")==false && StringUtils.contains(requestUri, contextPath+"/store/")){ String storeId = requestUri.replaceAll(contextPath+"/store/", ""); String url = "store.do?cmd=view&storeId=" + storeId; ((HttpServletResponse)response).sendRedirect(url); } chain.doFilter(request, response); } |

Manish - First time you got Jsession id in your URL but second time not. When first request came to your server, at that point server is not aware of whether you have enabled the cookies or not. So first time, it will send cookies as well as Jsession id. This is why you got Jsession id first time. On second ... |
I have some doubts in URL rewriting. I have made servlet UrlRewrite.java where I m using encodeURL() and then going to Page Hi.jsp. When clicked on link, I got Hi.jsp page and jsession id appended to the url. Then I clicked on link & went to bye.jsp But this time I go the output as "session is new" . Question : ... |
Jerei, This is typically something that you would track at the Web server layer rather than the application layer. You will achieve a greater amount of flexibility by tiering your architecture in this respect. You might want to have a look at the apache module mod_usertrack to achieve what you are trying to do. It depends on how and why you ... |
