http-status-code-301

问题 So, I've been working on a PHP link shortener (I know, just what the world needs). Basically when the page loads, php determines where it needs to go and sends a 301 Header to redirect the browser, like so... Header( "HTTP/1.1 301 Moved Permanently" ); header("Location: http://newsite.com"; Now, I'm trying to add some tracking to my redirects and insert some custom analytics data into a MySQL table before the redirect happen. It works perfectly if I don't specify the a redirect type and just

问题 My code is the following: <?php header("HTTP/1.1 301 Moved Permanently"); header("Location: http://newsite.com/"); ?> The issue I am having is several users have already reported the page not redirecting them and instead showing them the content on the old page, but later in the day it showed the correct redirect. I know it has to be related to the caching but which is the most efficient and standardized way to bypass the cache for the above redirect? Would I use php or javascript? Thank you.

问题 I currently have a small-midsize website with .htm extensions. I have redesigned the full website, this time using a .aspx extension. I want to issue 301 redirects to keep my search engine rankings, but am unsure of how to do so from an .html page in a spider friendly way. With research I have repeatedly encountered references to ISAPI redirects (but no where can I seem to find a full explanation, just a link to isapiredirect.com, which does not load). Other than this I have been advised to

问题 I am new to this so I will try to explain myself clearly. I am doing my 301 redirect from a custom 404 page. Now I got it working my question is more regarding how google would treat this. Cause we going to a 404 page would google just record it as a 40 page or would it actually record the 301? As i said I am new to this and have looked through google to try and find an answer to this. Anyway any help or comment would be greatly appriciated. thanks in advance 回答1: Best practice in this case

问题 Hi on redirecting of catalogsmain.asp I want to call Global.asax file and in that I want to call Application_BeginRequest method. Actual I have one old website which is created in old ASP so it contains all page with extension .asp. Now we had created that same website in MVC and now what we need to do is that when any user search on google and click to the SEO link it will open that site as www.abc.com/product.asp which will redirect it to IIS 404 error as product.asp page will not be there

问题 I'm using VBScript and the Microsoft.XMLHTTP object to scrape some web data. I have a list of URLs to check, but unfortunately some of them 301 redirect to others on the list, so I wind up with redundant data. Is it at all possible to make the XMLHTTP object fail on 301 redirect? Or at least cache the original response header? Or otherwise just let me know what happened? (notes: I have no control over the server I'm requesting data from; when I get new data, I could check if it's redundant,

问题 I'm trying to get HTML by URL in Java. But 301 Moved Permanently is all that I've got. Another URLs work. What's wrong? This is my code: hh= new URL("http://hh.ru"); in = new BufferedReader( new InputStreamReader(hh.openStream())); while ((inputLine = in.readLine()) != null) { sb.append(inputLine).append("\n"); str=sb.toString();//returns 301 } 回答1: You're facing a redirect to other URL. It's quite normal and web site may have many reasons to redirect you. Just follow the redirect based on

问题 Is the client supposed to behave differently? How? 回答1: Status 301 means that the resource (page) is moved permanently to a new location. The client/browser should not attempt to request the original location but use the new location from now on. Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url. 回答2: When a search engine spider finds 301 status code in the response header of a webpage, it understands
