http-status-code-301

问题 I'm running Apache 2.0 and I'm just wondering if it is possible to make a 301 redirect using JavaScript or jQuery. I have an <a></a> tag with href to a specified location and I'm asked to make a 301 redirect when I click that link. This is for SEO and I'm trying to find a way to do the 301 redirect to the same page in the link without having to create a new page or create a form/submit. 回答1: In short No . JavaScript runs entirely on the client side. 301 redirects are supposed to come as a

问题 I am debugging a problem with a HTTP 301 Permanent Redirect. After a quick test, it seems that Safari clears its cache of 301s when it is restarted, but Firefox does not. When do IE, Chrome, Firefox and Safari clear their cache of 301s? UPDATE: For example, if I want to redirect example1.com to example2.com , but I accidentally set it to redirect to example3.com , that is a problem. I can correct the mistake, but anyone who has visited example1.com in the meantime will have cached the

问题 I have a server over HTTPS on NodeJS with Express. When uploading a file, I have used the req.protocol directive in the controller to get either the HTTP or HTTPS "part" of the URL, so that I can save the file with the absolute URL. The problem is that without enabling the "trust proxy" setting of express (http://expressjs.com/en/api.html#trust.proxy.options.table), HTTPS doesn't get detected. I thought this setting was used in the case of the actual redirect (when using the HTTP URL and the

问题 Is there anyway to do 301 Redirect with custom message using .htaccess? Eg. Before the redirect begins, it will say: "We have moved permanently to abc.com and this domain will be expired soon. So please update your bookmark accordingly. You will be redirected in 10 seconds." Or that's only possible with PHP or other programming languages? 回答1: No -- because 301 code has to be issued on the server side. Browser/Search bot checks the response code and if code is 301 it will ignore any content

问题 I have some script in my default page that redirects users to language specific versions of my website depending on the language of the browser. I want to add something that redirects those users who do NOT have Javascript enabled. Currently I have the following : <noscript> <META HTTP-EQUIV=REFRESH CONTENT="1; URL=en/index.htm">. </noscript> But I've read this is not too wise as some search engines frown upon it.

问题 I have a dynamic page that I need to redirect to another dynamic page in .htaccess. I have tried different syntax for the redirect but nothing seems to work: RewriteEngine on RewriteRule /index.php?p=page&page_id=store$ http://www.website.com/index.php [R=301] OR RewriteEngine on RewriteCond %{QUERY_STRING} ^p=page&page_id=store$ RewriteRule ^/index.php$ http://www.website.com/index.php?

问题 I try to make a header redirect on an Google App engine instance with header("HTTP/1.1 301 Moved Permanently"); header("Location: http://".$location); header("Connection: close"); die(); It's working on my local development environment.

问题 I have my website hosted on the HTTP protocol, but my hosting service provides a default page when accessed through HTTPS. Since I'm not using SSL, from an SEO perspective, which one is more correct? a) toggle https for my website and do a 301 redirect to http://? b) just leave it like that (default https page from the web hosting co) 回答1: A would be the cleanest solution but it shouldn't really matter.
