So you want your WordPress site to allow you to have a different 404 error page for a subdirectory.  These instructions are for WordPress sites running on Apache.

The issue with adding custom 404 error pages to your WordPress site is due to WordPress using Apache’s rewrite on your entire site.  In order to prevent this from happening on your subdirectory, you need to add a .htaccess file with the following code:

<IfModule mod_rewrite.c>
RewriteEngine Off
</IfModule>

ErrorDocument 404 /subdirectory/404.html

This code prevents URL rewrites on your subdirectory, and specifies your custom 404 error page.  The 404 error page should link to the custom file you want to display to your visitors.

Step 1: Download and install Stunnel for Windows
http://www.stunnel.org/download/binaries.html

Step 2: Configuration
Stunnel needs to be configured to create a connection from the port which will allow remote connections (ie: 14333) to the Microsoft SQL Server port (1433). All connections to port 14333 on the server will be encrypted. On your server, set port 14333 to accept remote TCP connections, and make sure to block all remote connections to port 1433 from the Internet. Configuration may vary depending on your network structure, but only the secure port should be accessible from outside your network. You can even restrict access to the secure port further by only accepting connections from specific IP addresses.

Now, lets modify the Stunnel configuration file.  You can access the configuration file from the start menu in the stunnel program folder, there is an icon that says “Edit stunnel.conf”.

Paste the following into the stunnel configuration:

cert = stunnel.pem
debug = 7
output = stunnel.log

[mssql]
accept = EXTERNAL_IP:14333
connect = 127.0.0.1:1433

Replace EXTERNAL_IP with the IP address of your server. This configuration tells stunnel to use stunnel.pem for the security certificate – by default located under c:\program files\stunnel.pem. All debug output is logged to the stunnel.log file.
Make sure your MSSQL server accepts connections on 127.0.0.1 and port 1433, otherwise you may need to change this information, or modify your SQL configuration.
