[英]php htaccess redirect 404 error page
I am building a LAMP application www.testing.com
and I have an image url www.testing.com/image/folderA/a.jpg
. 我正在构建一个LAMP应用程序
www.testing.com
并且有一个图像URL www.testing.com/image/folderA/a.jpg
。
I want to have a rewrite rule in .htacess such that if user navigates to images that do not exist in /image/foldera, he will be redirected to another image with the url www.testing.com/image/folderB/b.jpg
. 我希望在.htacess中有一个重写规则,以便如果用户导航到/ image / foldera中不存在的图像,则他将被重定向到另一个具有URL
www.testing.com/image/folderB/b.jpg
图像。
This is my code. 这是我的代码。
RewriteRule ^image/folderA/(.*\.(jpg|gif|png))$ http://%{SERVER_NAME}/image/folderB/b.jpg [R=404,L]
However, this is not working as www.testing.com/image/folderA/a.jpg
, which is supposed to return an image, gives an 404. Any idea why? 但是,这不起作用,因为应该返回图像的
www.testing.com/image/folderA/a.jpg
给出404。为什么?
When using the R flag you need to keep the following in mind: 使用R标志时,请注意以下几点:
However, if a status code is outside the redirect range (300-399) then the substitution string is dropped entirely, and rewriting is stopped as if the L were used.
http://httpd.apache.org/docs/trunk/rewrite/flags.html#flag_r http://httpd.apache.org/docs/trunk/rewrite/flags.html#flag_r
This means that your rewrite rule is dropping the substition string and redirecting all requests to specified files to the built-in 404 page. 这意味着您的重写规则将删除替换字符串,并将所有请求重定向到指定的文件到内置404页面。
