This page documents the SOCKET_FILTERS configuration setting in FormMail.
Type Of Setting
SOCKET_FILTERS is an OPTIONAL setting, which means...
OPTIONAL : you can change this setting if you need to, but the default value is fine for most circumstances.
Précis
Defines filters available via HTTP or HTTPS.
Description
Set SOCKET_FILTERS to filter programs you want to access via HTTP or HTTPS connections.
Server Restrictions
Some server setups prevent the execution of external programs. Provided you can execute cgi-bin programs from a web browser (i.e. an HTTP connection), we've provided a workaround for this situation. FormMail can execute your cgi-bin filter program using an HTTP (or, if your PHP is configured correctly, an HTTPS) connection.
Accessing FormMailEncoder
SOCKET_FILTERS is supported by FormMailEncoder (fmencoder) version 1.4 and above only.
To execute fmencoder via HTTP, do this:
- Change the "site" value for "httpencode" to your site's web address.
- Upload your public key to the file "pubkey.txt" in your cgi-bin directory (or change the "file" setting in the "params" value).
- Add this hidden field to your HTML form:
This is still secure because the information never leaves your server in clear text form. However, if you need to execute fmencoder on another server (i.e. a server different from the one that has your FormMail script), you need to use the "sslencode" filter instead of the "httpencode" filter. Contact us for assistance if you require this.
