WWW Proxy

A proxy is an “intermediary” between client requests, e.g. the web browser running on your workstation, and the web servers that provide web pages. When using a proxy, the client does not send its request directly to the remote web servers, but to the proxy, which retrieves the pages from the web server and forwards them to the client. The proxy requests pages from remote computers using its own IP address. Your system's data remains hidden (anonymized).

For server systems that require special security, the proxy can also be used as the only approved interface to the Internet, e.g. to download updates.

For your browser proxy settings, use the proxy name proxy.uni-hamburg.de with port 3128.

The RRZ proxy service can only be used by clients from the university network.

The previous recommendation to generally use the proxy on workstation systems in the scientific network no longer applies. On the contrary, the proxy should only be used when explicitly required. The proxy no longer has any caching function and does not offer any significant security benefits for normal workstation systems. A number of software programs and databases that are licensed or approved for specific IP addresses cannot be used via the proxy. On workstations in the administrative network, however, it is necessary to use the special proxy configured there for access to the Internet; the proxy mentioned here cannot be used for this purpose.
