Mapping Portal Server Features to Your Business Needs
Feature | Description | Benefit |
Rewriter Proxy | Redirects HTTP requests to the Rewriter |
| Proxy instead of directly to the destination |
| host. The Rewriter Proxy in turn sends the |
| request to the destination server. |
Using the Rewriter Proxy enables secure HTTP traffic between the Gateway and intranet computers and offers two advantages:
•If a firewall exists between the Gateway and server, the firewall needs to open only two ports— one between the Gateway and the Rewriter Proxy, and another between the Gateway and the Portal Server.
• HTTP traffic is now secure between the Gateway and the intranet even if the destination server only supports HTTP protocol (no HTTPS).
Search Engine
The Search Engine service is used in the following channels:
•Subscription channel to summarize the number of hits (relevant information) that match each profile entry defined by the user for categorized documents and discussions.
•Discussion channel to individually search contents and rate the importance for comments.
