Java Servlet Filter redirect problem -


I am having trouble with my certification filter when the login login page redirects, if any image is displayed in JSP login Does not happen. However, if I go to the login page manually on the login page, images are displayed.

I do not understand why this is happening! I appreciate any help: -)

AuthFilter: 

  if (authorized == tap & amp; path.indexOf ("AUTH") = = -1 & amp; Index IndexOf ("Login") == -1) {httpResponse.sendRedirect ("Login"); Return; } And {chain.doFilter (request, response); } Login servlet:  
  // Just using a servicelet, I want to send more data to JSP Dispatcher.dispatch ("View / Login.jsp ", request, feedback);  
 
 login.jsp: 
 
  & lt; Img src = "picture / logo.png" />  
 
 jsp is otherwise "normal", all the required HTML tags are present. The "Images" folder is in the project's default "Web" folder, with all other jsp and javascripts. 
 
 Thanks in advance for any help.

This is due to relative path

  • Your log in is in the context of the
  • Your images may be / views / images /
  • As you move forward, The browser only knows the requested URL.

So when you move forward, the images are requested on / images> (because / views / images /

Two options:

  • Do not exceed your topmost; Redirect instead
  • Do not redirect from filter to servlet ; Directly redirect to login page

Update: Make sure images are not affected by filter Two options:

  • Filter them Pattern should not be matched
  • The filter should not have redirection for .png, .jpeg, .css, etc. It should be request.getRequestURI ()
    • Check with

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
