阅读更多关于 How to redirect from HTTPS to HTTP without annoying error messages

问题 I want to redirect users, after HTTPS login, to the HTTP pages on the site. Using HTTPS for the whole site is not going to happen. What I have so far is the following: User posts the login form to the secure site The secure server validates the credentials The secure server sends a 302 redirect to the client This works, except on my machine in IE6 the user gets an error message because the default is to warn when exiting a secure page. These errors are a usability killer for me and thus a

What does HTTP/1.1 302 mean exactly?

阅读更多关于 What does HTTP/1.1 302 mean exactly?

Some article I read once said that it means jumping (from one URI to another), but I detected this "302" even when there was actually no jumping at all! CodeMonkey1313 A 302 redirect means that the page was temporarily moved, while a 301 means that it was permanently moved. 301s are good for SEO value, while 302s aren't because 301s instruct clients to forget the value of the original URL, while the 302 keeps the value of the original and can thus potentially reduce the value by creating two, logically-distinct URLs that each produce the same content (search engines view them as distinct

问题 I have some includes on a login page, a css file and a js file. <link rel="stylesheet" type="text/css" href="../../ext/resources/css/ext-all.css" /> <script type="text/javascript" src="../../ext/bootstrap.js"></script> Unfortunately the requests the browser makes for these get the 302 response.

I have a reverse proxy that checks global authentication for several applications. When the user is disconnected but still trying to use my application, the proxy sends a 302 response : HTTP/1.1 302 Found Date: Wed, 11 Sep 2013 09:05:34 GMT Cache-Control: no-store Location: https://other.url.com/globalLoginPage.html Content-Length: 561 Content-Type: text/html; charset=iso-8859-1 Via: 1.1 my-proxy.com Connection: Keep-Alive In angularJs, the error callback is called but the response headers are empty, status is 0 and data is an empty string. So it seems that I really can't do nothing to handle

Intercepting backend 301/302 redirects (proxy_pass) and rewriting to another location block possible?

阅读更多关于 Intercepting backend 301/302 redirects (proxy_pass) and rewriting to another location block possible?

问题 We have a couple of backends sitting behind our nginx front ends. Is it possible to intercept 301 / 302 redirects sent by these backends and have nginx handle them? We were thinging something alone the lines of: error_page 302 = @target; But I doubt 301/302 redirects can be handled the same as 404's etc etc... I mean, error_page probably doesnt apply to 200, etc error codes? So to summarize: Our backends send back 301/302s once in a while. We would like to have nginx intercept these, and

问题 I'm trying to write a program to do automated testing on my webapp. To accomplish this, I open up a connection using HttpURLConnection.

问题 Using WebRequest I want to know if I get a "302 Moved Temporarily" response instead of automatically get the new url. 回答1: If you want to detect a redirect response, instead of following it automatically create the WebRequest and set the AllowAutoRedirect property to false : HttpWebRequest request = WebRequest.Create(someUrl) as HttpWebRequest; request.AllowAutoRedirect = false; HttpWebResponse response = request.GetResponse() as HttpWebResponse; if (response.StatusCode == HttpStatusCode

I use jQuery to make an AJAX POST request to my server, which can return HTTP response with status 302. Then JavaScript just sends GET request to this URL, while I'd like to redirect user to URL in this response. Is this possible? Steg The accepted answer does not work for the reasons given. I posted a comment with a link to a question that described a hack to get round the problem of the 302 being transparently handled by the browser: How to manage a redirect request after a jQuery Ajax call However, it is a bit of a dirty hack and after much digging around I found what I think is a better

问题 Are there any issues with sending back a cookie during a 302 redirect? For example, if I create a return-to-url cookie and redirect the user in the same response will any (modern) browser ignore the cookie? 回答1: Most browser are accepting cookies on 302 redirects.
