1. Proxy errors occur when an organization configures its primary proxy ISA server to filter hypertext transfers, extensions or signatures supported by protocol content.
Therefore, whenever you or any member of your organization tries to access a bound URL on the network, the organization's main proxy server creates a proxy error message.
Error messages are sometimes messages sent to your laptop via proxy servers from the largest network networks. The agent error is indicated by error code 502.
Proxy errors indicate that Web users are not allowed to access specific Web sites or generic resource locators. This restriction is enforced by the organization's network administrator or website /URL creator to protect non-public content, that is, viewable by specific individuals only.
