Referers

"Referers" is the feature that denies access to Form Processor Pro from domains that are not listed. This feature is optional. If it is set, the form can be submitted only from the specified domains. Otherwise submissions for all domains are allowed.

Example:

You can specify multiple domains separated by commas. You can use "localhost" for a referer if the form is located on the same server as Form Processor Pro is.

Also you can specify what protocols can be used to submit the form. By default both http:// and https:// are allowed, but you can impose a restriction.
