Many Webmin modules are capable of downloading files from other FTP, HTTP, and HTTPS servers. For example, the Software Packages module lets you enter a URL from which you can fetch and install a new package. Webmin will normally connect directly to the host specified in the URL, but it can be configured to use a proxy server instead. This may be necessary if your network does not allow direct access to web and FTP sites, but instead forces clients to connect through a proxy.
Webmin's RPC mechanism (covered in Chapter 53) also makes use of HTTP requests to other Webmin servers. Any proxy configuration will also apply to RPC calls, although it will not direct TCP connections used by the RPC protocol when in fast mode or when transferring large files. Because any other Webmin servers are likely to be on the same network, you will probably want to disable the user of a proxy for those hosts.
To specify HTTP and FTP proxy servers and the hosts for which they will be used, follow these steps:
