Firefox does not preserve custom headers during Ajax request redirect: an ASP.NET MVC solution -

-

I use ajaxform with jj, and there is a problem with firefox - for some reasons this x -requested - Custom header (used to detect IsAjaxRequest () ). Returns IsAjasxRequest () after redirection.

This bug is only in Firefox, for example it works fine in Chrome.

You can see the mention of this bug. A very old post, I wonder why it still happens to me (I use Firefox 3.5.3) Anyway, here's my solution - in my Base Controller class: 

  Protected Override Zero Onset Exposing (Action Expating Contact Filter Contrax) {var ajaxRequestBeforeRedirect = TempData ["__ isajaxrequest"] in the form of a string; If requested (ajaxRequestBeforeRedirect! = Null) Header. Add ("Ex-Requested", ajaxRequestBeforeRedirect); } Private Bull IRDADRR Results (Action Result Results) {Return Results Gate type () Name. TOOLAV () This includes ("redire"); } Protected Override Zero On-Off Acne (Actioned Contact Filter Filter) {base.OnActionAxecuted (filterContext); If (IRDERCIRCilt (filtercontact.Reject) and request.header ["X-requested-with"]! = Null) tempadata ["__execrequest"] = request Header ["x-requested-with"]; }

This works; However, I have two questions here:

  1. Is this bug really fixed in Firefox or I do not understand anything?
  2. Is this a good solution? Is there any better? I believe nobody had this problem before before.

Update: For those who are interested in this issue, request. Header. Add IIS6 (or maybe IIS5, but anyway). So this template data / HTTPContacts correctly. The "isAjaxRequest" flag must be stored in the item / base controller.

Just another person is questioning why their header-based dispatching is unsuccessful in Firefox , It is not certain that it has been tested in Firefox 3.6.10, as is not fixed in 2010-10-11

related bugs, and today's latest comments (by Jonas, 2010 Created on -09-16) This problem will be fixed in not in Firefox 4.

In addition to this, this bug is standard settings headers like Acceptable, which means a Accept: Application / Jason will disappear after a Redirect and your XHR engine may Instead, you will get an HTML response.

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol.

It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
