IIS7 Displays BOTH Its Own 404 Message & CF9 Message; Should Display Just Its Own

阅读更多关于 IIS7 Displays BOTH Its Own 404 Message & CF9 Message; Should Display Just Its Own

问题 My goal seems simple. I want IIS 7.5 to handle ALL 404 File Not Found requests, whether to static or dynamic (ColdFusion 9) content, and direct users to its custom 404 HTML page. I believe that the IIS settings I need are existingReponse=Replace , errorMode=Custom , and a file path specified for the 404. That's what I've done. With a ColdFusion 10 install, it works. With ColdFusion 9, for some reason both the static IIS 404 response AND the ColdFusion 404 response are sent to the client and

ASP.NET Custom 404 Returning 200 OK Instead of 404 Not Found

阅读更多关于 ASP.NET Custom 404 Returning 200 OK Instead of 404 Not Found

After trying to setup my site for Google Webmaster Tools I found that my Custom ASP.NET 404 page was not returning the 404 status code. It displayed the correct custom page and told the browser that everything is OK. This is consider a soft 404 or false 404. Google doesn't like this. So I found many articles on the issue but the solution I want didn't seem to work. The solution I want to work is adding the following two lines to the code behind Page_Load method of the custom 404 page. Response.Status = "404 Not Found"; Response.StatusCode = 404; This doesn't work. The page still returns 200 OK

How do I force redirect all 404's (or every page, whether invalid or not) to the homepage?

阅读更多关于 How do I force redirect all 404's (or every page, whether invalid or not) to the homepage?

问题 Currently every invalid page is 500 (Internal Server Error) because I probably messed up with my server block configuration. I decided to shut down my website a while ago and created a simple one-page, thank-you homepage. However old links and external sites are still trying to access other parts of the site, which no longer exists. How do I force redirect all non-homepage (any invalid URL) to the homepage? I tried with the following block, but it didn't work: location / { try_files $uri $uri

How do I return NotFound() IHttpActionResult with an error message or exception?

阅读更多关于 How do I return NotFound() IHttpActionResult with an error message or exception?

问题 I am returning a NotFound IHttpActionResult , when something is not found in my WebApi GET action. Along with this response, I want to send a custom message and/or the exception message (if any). The current ApiController 's NotFound() method does not provide an overload to pass a message. Is there any way of doing this? or I will have to write my own custom IHttpActionResult ? 回答1: You'd need to write your own action result if you want to customize the response message shape. We wanted to

问题 I'm trying to host a new blog where I can add posts using a simple HTML form & PHP script. When I test out the form on my localhost everything works fine, but when I upload it and test it live I get: Forbidden You don't have permission to access /php/add-post.php on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. I know that my host allows this type of script because I'm using exactly the same thing on another blog,

How to callback a function on 404 in JSON ajax request with jQuery?

阅读更多关于 How to callback a function on 404 in JSON ajax request with jQuery?

问题 I want to make an Ajax request with response in JSON. So I made this Ajax request: $.ajax({ url: 'http://my_url', dataType: "json", success: function(data){ alert('success'); }, error: function(data){ alert('error'); }, complete: function(data) { alert('complete') }}) This code works good but when my url send me a HTTP code 404, no callbacks are used, even the complete callback. After research, it's because my dataType is 'json' so 404 return is HTML and the JSON parsing failed. So no

Accessing original URL in IIS7 404 redirect page

阅读更多关于 Accessing original URL in IIS7 404 redirect page

问题 I have an .aspx page as my custom 404 page on a site set up on IIS 7. I need to retrieve the original URL that the user was trying to access in order to do some processing on the 404 page. The trick is that I need to specifically handle 404's that do not contain a .aspx extension (e.g http://example.com/testurl ), which do not get routed through ASP.NET's custom errors section. I can configure IIS to point to my custom 404, but at that point I do not know how to get my original URL? Does

404 header - HTTP 1.0 or 1.1?

阅读更多关于 404 header - HTTP 1.0 or 1.1?

Why does almost every example I can find (including this question from about a year ago) say that a 404 header should be HTTP/1.0 404 Not Found when we've really been using HTTP 1.1 for over a decade? Is there any reason not to send HTTP/1.1 404 Not Found instead? (Not that it matters all that much... I'm mostly just curious.) The usage of HTTP version can be based on the following factors: Your web server support for HTTP 1.0 or 1.1 The web browser's support for HTTP 1.0 or 1.1 Your preference as a web developer on which protocol version to use Modern browsers can support both 1.0 and 1.1

阅读更多关于 include after PHP 404 header returning “Oops! This link appears to be broken.”

问题 To make a long story short, I have dynamic pages on a website that display reviews. If there are no reviews associated with a particular city/county/area/etc the mysql query returns 0 rows which triggers the following code: if (!$validRevQuery) { header("HTTP/1.0 404 Not Found"); include("http://{$PDS['site']}/404.php?request=".urlencode($_SERVER['REQUEST_URI'])); exit; } On some webhosts this triggers a "URL file-access is disabled" error. Which is fine, but on the ones that allow URL file
