I wish to redirect "http://localhost/b.html" --> "http://localhost/a.html" I attempted RewriteRule for your. But in some way it's not employed by me.

I'm using apache2 and my httpd.conf consists of:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule rewrite_module modules/mod_rewrite.so

RewriteEngine On
RewriteRule ^/b.html$ http://localhost/a.html

After I tri "http://localhost/a.html" It shows me the site. However when I triend "http://localhost/b.html" apache2/error_log states "file doesn't exist: b.html" Does any setting missing make it possible for rewrite_module?

The issue is inside your RewriteRule. this will work:

RewriteEngine On
RewriteRule ^/b.html$ /a.html [L]
  1. the rule match (^b.html$) mustn't range from the beginning slash. (this works inshtaccess, although not in server config)
  2. the rewrite target ought to be a family member URI if at all possible (i.e. on a single host)
  3. the rule should finish having a directive "how to proceedInch - within this situation [L]eave processing (forget about rules is going to be processed)

Perhaps you have checked whether inside your Apache configuration file (probably httpd.conf) the directive for that Alias or VirtualHost section:

AllowOverwrite All

I'd exactly the same problem of modrewrite no longer working because I'd them back:

AllowOverwrite None

Best of luck.

Have you got it within the virtualhost section?

<VirtualHost *:80>
    RewriteEngine On
    RewriteRule ^/b.html$ /a.html
</VirtualHost>

It really works now. Needed to do a couple of things:

  1. Change "AllowOverride None" in /etc/apache2/sites-available/default to "AllowOverride All".

  2. Place the rewrite rule in /var/www/.htaccess rather than httpd.conf

I don't know why it doesn't works in httpd.conf. However it works after doing the above mentioned a couple of things.
