More Information on the Library ClientProxy Service

Why does the Library offer the ClientProxy Service?

Many of the Penn Library's resource providers limit access through a process called "domain restriction," which restricts access to computer hosts within the "Penn Domain." For the provider, this is currently the most efficient way to enforce licensing restrictions over the Internet.

How does this affect me?

Unfortunately, vendor implementations of "domain restriction" on licensed resources means that Library patrons using computers that connect to the internet through commercial Internet Service Providers (ISP) will be denied access by the resource provider's site. This is because the Internet address (IP address) provided to the user's computer by the ISP is not in the "Penn Domain," and so, appears to be not licensed to access the selected resource.

This domain restriction is used by vendors such as Beilstein and CAS for their client programs Beilstein Commander and SciFinder Scholar.

What can I do to access these restricted resources from a non-Penn Domain computer?

Penn faculty, students or staff who use an ISP or network other than PennNet, can use the Library's ClientProxy Service to access restricted resources. The Penn Library ClientProxy Server is, in essence, a machine that forwards requests for resource from authorized users. The proxy server authorizes you against your record in the Library's patron database, and then serves as a "proxy" between your machine and the resource provider's site. Since the proxy machine is part of the "Penn Domain" mentioned above, the resource provider allows the connection.

If I have already setup my browser for the Library Proxy Service, do I need to worry about the ClientProxy Service?

Yes! The ClientProxy Service is similar to the Library Proxy Service but provides proxy service to non-web browser clients. Whereas the Library Proxy Service allows your browser to use domain restricted resources -- the Library ClientProxy Service allows non-web browser clients like Beilstein Commander and SciFinder Scholar to use domain restricted resources.
