Calling an external URL from cProject

Hello PPM Experts,

We want few of the cProject objects (e.g. checklist items, tasks) to point out to an external web pages (i.e. URL).

I guess I need to use "object links" tab for this and define a custom object type (say, ZEXTURL) in the IMG node 'Define Object Types for Object Links'.

Is this a correct approach or is there any other way?

Also, for the object link ZEXTURL, please let me know what should I enter in following fields of the IMG node.

Key

Identification

Proxy Class

Web Server

We want to achieve this without any coding / custom development. Please let me know whether that would be possible.

Regards,

Bhushan
