C# - Detecting If Referrer Was From A 301 Permanent Redirect?
Jul 8, 2010
I am doing a 301 permanent redirect from an old server to a new server. When the new server's page is hit I want to be able to determine whether the user comes from the old site and then react differently, i.e. instruct user to re-book mark the new page.
Our old ASP.net site stored static images in a sub directory on the root called /images.
Our new ASP.net MVC site stores these images in the new layout of /Content/Images
I've changed all the pages in the site to cope with the new folder structure, but I'd like to set up Permanent Redirects from the old static images to the new location.
I have an existing web site and I would like to create a mobile version of it that is more suitable. For instance, the main site uses drop-down menus and we all know those are quite the fail on mobile devices.I would like to redirect to my mobile version (it will be a subdomain of the current site) if I detect a request from a mobile browser. So when they Google something and come to my site, they will automatically see the mobile version (just like Wikipedia).Does ASP.NET provide an easy way of doing this
I upgraded my site from asp to asp.net.This means that all of my previous asp files became obsolete.I don't want to lose my Google Ranking of the old pages.
What is the proper way to redirect?I tried to catch all of the old asp pages is my 404 and then to:
if Request.QueryString("aspxerrorpath").contains("index.asp") = true then Response.Status = "301 Moved Permanently" Response.AddHeader("Location", "http://www.domain.com/index.aspx") Response.Redirect("/index.aspx") end if
I picked up a new-to-me client who had a site built in ASP.net (which I do not host).I converted the site to PHP, which worked fine.I want to set up redirects for all the pages he had in the old site (it was a small site, so there was only 8 pages).As an example, the ASP.net url for the Contact page was www.domain.com/Contact - it is now www.domain.com/Contact.php (and so on).
For 301 redirects from one PHP page to another I normally use the .htaccess file:
I need to keep my basket more permanent I have two options and I want to choose the best one.
I have eCommerce web site application in asp.net and there is a basket include products which are selected by users before, so options:
1- keep basket in database (consider the cost and time to store and retrieve information) 2- store my basket in Cookies (I don't know what the implementation is)
I couldn't use session because it is not permanent and clear by closing browser.
My goal is : when the user close the IE for 1 day or 2 days make ability to remember all products that already added to basket.
In addition, my basket is store in hash-table now, for example : {1:4055,2:4588,...} they are ID and product code(keys). they are all save in a hash table.
Am building an dll which contains a function called geturl(Uri myuri), Uri as parameter. Basically i want to get the url of the page which calls this function(function is located on DLL). I have used the below code, but am not sure the page url can be overrided //In default.aspx //class declaration myclass mc = new myclass(); Uri ur = Request.Url; string str = mc.geturl(ur) //In DLL public string geturl(Uri myuri) { Uri MyUrl = myuri; string requrl = MyUrl.AbsoluteUri.ToString(); return requrl; } So my question is can the Uri on the default.aspx be assigned with custom url as [URL] instead of http://localhost/test/default.aspx
Our old site is in Classic ASP, and we know there are many people who have pages bookmarked. The new pages will be written in .Net.I thought of url rewriting (overkill?), but I'm not sure how to set that up (if this is the best way, I'll need some links to tutorials for using it in this specific manner. I've seen it used by never done it myself)What is the best, most efficient way setup some permanent redirects for these .asp to aspx pages?
I have a page which I only want to be accessable via a certain other page.Example, PageTwo.aspx can only be accessed via PageOne.aspxAll other referrers redirect to asp.netCan this be done in asp?
I'm currently testing my application and am stuck on trying to figure out how to create a custom fake URL referrer. I've tried to hard code it, but am getting an error that it is read-only. Here is what I've tried so far:
fakeController.HttpContext.Request.UrlReferrer.AbsolutePath = "http://www.yahoo.com"; as well as, fakeController.Request.UrlReferrer = "http://www.yahoo.com";
I've searched the web for some ideas on how to create a fake/mock URL referrer for my fake controller, but have had no luck.
Note: I'm using Visual Studios built-in unit testing facilities.
UPDATE:
I would be more than willing to use any other unit testing system outside of Visual Studio, unfortunately here at my work we are only allowed to use Visual Studio's built-in system, so I gotta work with what I've got.
We have a scenario whereby we are hosting an ASP.NET MVC web site on behalf of someone else.The customer in this case wants us to restrict access to the web site, to those users who have logged in to their main portal. They should then only be able to get to our web site via a link from that portal.At this point I'm not yet sure what technology or authentication mechanism the 3rd party are using but just wanted to clarify what the possible options might be.If we call our hosted site B, and their portal web site A,as I see it we could:Check the referrer for all requests to B, unless they've come from A they can't get inCheck for a specific cookie (assuming A uses cookies)
I need to get the calling page url referrer and host name. I works for me if the calling pages are within the same network. When a page is called from an internal site that are outside of my network, I got the following error:
Object reference not set to an instance of an object.
When I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.
In the OnLoad(EventArgs e) event -- I'm trying to do this, but it appears to be too late.this.txtReferrer.Text = Request.UrlReferrer.ToString();Is it possible to capture the referrer url?
The idea is that if the user does not have JavaScript enabled, they see a brief loading message, and the home page loads after a second. If JavaScript is enabled, the page reloads instantly. In the future I could even post to the server the dimensions of the viewport and such. Does this look like it would work? If the window.location command takes longer than a second to run, will it be interrupted by the meta refresh, or does it block that refresh? I am hoping the latter, so I don't need to increase the delay for those non-js people.
I figure my new way adds a little extra weight to the payload of the redirect, but it's not an extra round-trip or anything, is it? The redirect happens anyway, does it not? Update: I neglected to mention a very important point. I do not actually have control over the login screen itself, only the page it posts to. This code is part of a product that relies on an external authentication mechanism.
So I'd like to redirect mobile users to a different page. But instead of trying to detect any number of mobile browsers, I'd just like to see if the user is using IE, Firefox, Safari, Chrome, or Opera; all other users go to the mobile site. My biggest problem is detecting regular Safari from mobile Safari.
i'm programming an application where an action is done if i access with a version equal or higher than other and another action if i access with a lower version; but the problem is that the lines to indicate the versions doesn´t work. The code is the following:
[Code]....
As you can see, an action should be done if the version is the 9.0 or higher and other if it is lower, but these lines doesn't work and only works the detection of the web browsers (no the versions of them, action that doesn't works).
I'm developing an extra section to a web app that's written in asp.net, but in php - it's mostly done (the two parts don't really communicate with each other outside of a database - the integration is mostly just cosmetic.)
The only issue I have is detecting from the php part when the .net session has expired so that it logs the user out and redirects to the login page.
I believe the asp.net application is compiled, but either way I'm not allowed to alter it so I was thinking maybe the best thing to do would be to make a very small/simple aspx page that outputs true or false which I could call using curl from php (and passing the browser's cookies along.)
Would this even be possible? I'm not sure how session security works on asp.net eg whether one .net application can read another's session variables, but if it's anything like php then it'll be possible.
So mypage issues a GET (with cookies from browser) to checksession using curl, checksession simply returns a true or false (or something like that) and mypage redirects to the site's login page if that's false.
The authentication for the php side is already sorted out and is separate to this issue.
So really, what I need to know is can I have just a simple .aspx file that does this check, and if so where would I go to to find out how to program such a simple page?
Is there a way to detect if the user closes the browser/popup page? I am trying to implement a chat functionality by when the user closes the browser/page, I will update the flag in the database from active to not active. But I cannot seem to find a better way to handle that besides from detecting if the user closes the page.
I'm working on an ASP.NET web application. There's a bill page which has two links to different pdfs of the same bill. When you click on one of the links it takes you to a ViewPDF.aspx page that shows the pdf. There's also an option to view both in a split screen so that you can compare them. When you click on this link it takes you to BillSplit.aspx which has a frameset and two frames that both point to ViewPDF.aspx. This all works perfectly.
The problem is that if an error occurs while pulling up the pdf. The application has an error page that has a few links back into the application. If you use one of these you can go back into the app and continue but now inside the frame. The URL still says BillSplit.aspx but the application is completely unaware of this since frames are HTML elements not asp.net controls.
What I would like to do at this point is detect that you've returned to the application and close the frame you aren't using. Essentially I'd like to redirect you away from BillSplit.aspx and to the page you're actually requesting. I'm pretty sure this would need to be done in Javascript either on the BillSplit page or on the pages that you go to later. So I guess what I'm asking is, is there a way to ensure that the BillSplit.aspx page and it's two frames point only at ViewPDF.aspx?
