Caching of proxy auto-configuration results by domain name in Microsoft's Internet Explorer 5.5 or newer limits the flexibility of the PAC standard. In effect, you can choose the proxy based on the domain name, but not on the path of the URL. Alternatively, you need to disable caching of proxy auto-configuration results by editing the registry.

Proxy auto-config (PAC) standard: create and publish one central proxy configuration file. Details are discussed in a separate article. Web Proxy Auto-Discovery Protocol (WPAD) standard: ensure that an organization's browsers will find this file without manual configuration. This is the topic of this article.
HTTP/3 is the third major version of the Hypertext Transfer Protocol used to exchange information on the World Wide Web, complementing the widely-deployed HTTP/1.1 and HTTP/2. Unlike previous versions which relied on the well-established TCP (published in 1974), [ 2 ] HTTP/3 uses QUIC (officially introduced in 2021), [ 3 ] a multiplexed ...
Any data sent to the proxy server is now forwarded, unmodified, to the remote host [3] and the client can communicate using any protocol accepted by the remote host. In the example below, the client is starting SSH communications, as hinted at by the port number in the initial CONNECT request. SSH-2.0-OpenSSH_4.3\r\n ...
In computer programming, the proxy pattern is a software design pattern. A proxy , in its most general form, is a class functioning as an interface to something else. The proxy could interface to anything: a network connection, a large object in memory, a file, or some other resource that is expensive or impossible to duplicate.
However, most servers, clients, and proxy software impose some limits for practical and security reasons. For example, the Apache 2.3 server by default limits the size of each field to 8,190 bytes, and there can be at most 100 header fields in a single request. [10]
The general format of the field is: [2] X-Forwarded-For: client, proxy1, proxy2 where the value is a comma+space separated list of IP addresses, the left-most being the original client, and each successive proxy that passed the request adding the IP address where it received the request from.
A proxy list is a list of open HTTP/HTTPS/SOCKS proxy servers all on one website. Proxies allow users to make indirect network connections to other computer network services. [ 1 ] Proxy lists include the IP addresses of computers hosting open proxy servers, meaning that these proxy servers are available to anyone on the internet.
