Can I serve my CGI locally only?

I have a CGI app, UMN Mapserver, run by apache on my WebFaction account. To test my build and install, the Static App is tied to a Website that is publicly visible. All good! Moving forward I would like to run this CGI privately, other apps in my WF install would query it, but it should not be externally visible.

I do this on my elsewhere by serving Mapserver on an off-port and firewalling it. Is this possible to configure on WebFaction? Or is there a way that makes more sense on WebFaction?

Thanks!

You could use mod_rewrite to check HTTP_REFERER and/or REMOTE_ADDR, and reject any requests that don't come from the referrer and IP you specify.

This worked, thank you:

RewriteEngine on RewriteCond %{REMOTE_ADDR} !^2607:X:X::::X$ RewriteRule ^(.*)$ - [F,L]

Before reading this, I tried using Limit which is preferable for maintaining a whitelist, but could not successfully specify localhost or the local interface. It looked like:

<Limit GET POST> Order deny,allow Deny from all Allow from 199.XX.XX.XX Allow from 2607:X:X::::X </Limit>

My external IP address would be allowed, but not the local ipv6 address shown as my test wget client, nor 127.0.0.1, nor ::1, would hit for Allow. The syntax is fine, an "Allow all" would serve the local test client. Any idea why, does this have to do with the WF config?

0	You would have to build an apache server to do this without it being public. Or call the script in shell. permanent link answered 11 Feb '15, 05:52 johns 5.4k●4●12 accept rate: 23%
