How to set the 404 error page in htaccess

Setting the 404 error page for Apache Server is simple. You only need to add the following code to the. htaccess file:

The Code is as follows:	Copy code
ErrorDocument 404/notfound.html

Note:
1. Do not redirect the 404 error to the website homepage. Otherwise, the homepage may disappear from the seo/seo.html "target =" _ blank "> search engine.
2. Do not use an absolute URL (for example, http://www.hzhuti.com/nokia/n96/form). If you use an absolute URL, the returned status code is "302" + "200" (tested)

The correct method is to add the following code to. htaccess:

 

The Code is as follows:	Copy code
1 ErrorDocument 404/404 .htm Instead: 1 ErrorDocument 404 http://www.xxx.com/404.htm

The former returns a 404 status code,

The latter returns a 200 status code. If the content of a 404 page is smaller than 404 B, IE considers the 404 page unfriendly and will not return the error page in IE.

Add a backslash at the end of the URL in htaccess

Add the following code to the htaccess file:

The Code is as follows:	Copy code
IfModule mod_rewrite.c RewriteCond % {REQUEST_URI}/+ [^.] + $ RewriteRule ^ (. + [^/]) $ % {REQUEST_URI}/[R = 301, L] /IfModule

301 redirect. htaccess will jump to the URL with www without www

In htaccess, replace pcjs.cn with your url:

The Code is as follows:	Copy code
Options + FollowSymLinks RewriteEngine on RewriteCond % {http_host} ^ bKjia. c0m [NC] RewriteRule ^ (. *) $ http://www.bKjia. c0m/$1 [R = 301, L]

Use. htaccess anti-leech

The premise is that the mod_rewrite module in Apache is activated. Since we want to eliminate the mp3 file leeching, we also set the image leeching. below is my website root directory. the configuration in the htaccess file is for the reference of the person who is suffering from illness:

Code in the. htaccess file:

The Code is as follows:	Copy code
RewriteEngine on RewriteCond % {HTTP_REFERER }! ^ Http: // (www .)? BKjia. c0m/. * $ [NC] RewriteRule. (txt | doc | jpg | gif | mp3 | zip | rar | png) $ http://www.bKjia. c0m [R = 301, L]

Function: not only does the website block/prohibit unauthorized access to the website, but also transfers the request to its own website to let readers know who is the real author.

Code Description:
RewriteCond condition: It means all mp3, rar, images, etc. If the referer is not the website pcjs.cn or www.pcjs.cn,
RewriteRule rules: automatically go to the home page of this site

The commented out part is used to test the rewrite engine: It is useful for debugging mod_rewrite.

For other anti-leech settings, refer:

The Code is as follows:

Copy code

# Enable the mod_rewrite Engine RewriteEngine On # Set valid request sources RewriteCond % {HTTP_REFERER }! ^ $ [NC] RewriteCond % {HTTP_REFERER }! Hzhuti.com [NC] RewriteCond % {HTTP_REFERER }!
