I believe that 301 redirection is beneficial to weight concentration, but I wrote: & amp; nbsp; Rewri in the. htaccess file.
I believe that 301 redirection is known to everyone, which is conducive to weight concentration, but I wrote in the. htaccess file:
RewriteEngine on
RewriteCond % {http_host} ^ phpddt.com [NC]
RewriteRule ^ (. *) $ http://www.phpddt.com/#1 [L, R = 301]
After uploading the root directory of the server, it will be ineffective. the rewrite_module must not be enabled. the enabling process is as follows:
Centos configuration files are stored in:/etc/httpd/conf/httpd. conf
Open the file and find:
LoadModule rewrite_module modules/mod_rewrite.so
Remove the preceding "#". if it does not exist, add the above sentence.
If your website is in the root directory: find
Options FollowSymLinks
AllowOverride None
Change None to All.
If your site is not in the root directory, set as follows:
Order allow, deny
Allow from all
AllowOverride All
OK, then restart the server, and the service httpd restart, so that. htaccess can be used.
