How to allow access to an html file from the private network only?

[nregi]

Hello,

I have 2 web applications running on Tomcat.
One is accessed via the public ip and the other should be accessible only via the private ip.
Is there a way to tell tomcat to deny access to an html folder or files through the public ip?

Thank you.

I can tell you how to do it if you are using Apache as your front end, but purely Tomcat, I don't know.

The easiest way would be to configure your firewall so that port 80/8080 or whatever you have tomcat running on is not publically visible.

sedj,

But I need one of the html page accessible from anywhere.
I only want one html folder restricted to private network, the others can be accessed from anywhere.

This can be solved only through tomcat config if possible,
I thought of restricting it through a servlet, but someone can access the html pages if the path is known.

Thanks.

Not if you write the servlet properly.

I would recommend you use Apache as the front end to Tomcat. There's a reason they chose not to implement a lot of functionality in Tomcat, because it is already done perfectly well in other applications.

With apache you can bind one virtual host to one interface and a different one to another, then the public can't get to the private interface.

I think it would take you far less time to get a simple Apache config working than to try to hack together a pure Tomcat solution.

Failing that then, look into a writing a Filter - you can intercept all HTTP requests that way, determine the resource they want & their IP, and then act accordingly :
