Check my proxy server
Businesses often have proxies for security purposes.
A proxy server acts sort of like a middleman between your browser and servers that display Web pages. They do this by receiving page or link requests from your browser and then passing them to the Web server that hosts them. Many businesses use proxy servers to block access to certain sites or provide network users with more anonymity while surfing the Web. However, some sites restrict access to computers that connect through a proxy server. If you are having trouble accessing some sites, it might be because your computer connects through a proxy. Therefore, if you are having access problems, you should know how to determine whether your computer connects through a proxy.
1. Launch Mozilla Firefox on your computer. Click “Tools, ” click “Options” and choose "Options from the menu that slides out.
2. Click the “Advanced” tab in the Options window. Click the “Settings” button in the Connection box.
3. Locate the selected connection option in the list on the Connection tab. If your Internet connection uses no proxy server, the “No Proxy” connection setting option is enabled. If either the “Use System Proxy Settings” or “Manual Proxy Configuration” setting is selected, then your computer accesses the Internet via a proxy server.
1. Open Internet Explorer.
2. Click the “Tools” drop-down arrow in the upper-right portion of the browser window. Select “Internet Options.”
3. Click the “Connections” tab in the Internet Options window. Click the “LAN Settings” button. If there is a check mark in the box next to the “Us a proxy server for your LAN” option, then your PC accesses the Web through a proxy server. If there is no check mark in the box, your computer does not use a proxy server.
