A proxy server is a computer that can, for example
- Store local copies of Web pages so that a group of people (such as employees or subscribers) can get quick access to often-visited Web pages
- Act as an interpreter between your browser and a special service
- Alter or monitor information exchange
- Speed up Internet communication
Click and enter the necessary information. All traffic using the respective protocol will now go through the proxy server you specify.
To use a proxy, you need to specify:
- A protocol (such as HTTP)
- An Internet address (such as proxy.example.org or 18.104.22.168)
- A port number (such as 5000)
You can get this information from your Internet service provider (ISP), the host of your proxy server, or the documentation that comes with your proxy software.
To access certain sites without going through the proxy, you can enter a list of Web addresses to exclude.
If your Internet provider requires automatic proxy, please enter the Web address provided by your ISP.
Server Name Completion
When you enter a single word (for example "opera") in Opera's address field, Opera will:
- Look for a bookmark nicknamed "opera"
- Look for a computer in your local network called "opera"
- Attempt server name completion by adding prefixes (such as "www") and suffixes (for example "com") to look up "www.opera.com"
You can enter comma-separated lists of prefixes and suffixes. You may for example want to add the top-level domain of your home country to the list of suffixes.
Note: It takes time to try multiple combinations; if your connection is slow, you may want to turn this feature off for faster browsing.
Tip: To skip directly to server name completion by prefix and suffix, press Ctrl+Enter.
International Web addresses
Some servers may prefer that Opera encodes the address in local character encoding (like latin-1) instead of the recommended UTF-8 encoding.
|Address in latin-1||http://www.example.org/%E6%F8%E5.html|
|Address in UTF-8||http://www.example.org/%C3%A6%C3%B8%C3%A5.html|
Some Web sites make a note of which page you came from, and behave accordingly. Turn referrer logging off if you do not want one site to know which other site you just came from.
Note: Some sites depend on referrer logging to work properly.
Some Web pages automatically redirect you to another page or site. Disable automatic redirection if you would rather stay in control by clicking redirection links.
Try changing the maximum numbers of connections to servers if you are experiencing problems with browsing speed. Otherwise, it is recommended to keep the default settings of 8 and 20.
Network preferences can also be specified per site. In addition to the encoding, referrer, and redirection settings, the network site preferences also offer the option of changing how Opera presents itself to the site.
When a Web browser connects to a Web site, it tells the site which browser it is. Some Web sites will then provide content tailored for particular browsers. However, as browsers are in constant development, assumptions made by site designers may not always have the intended effect.
If you experience problems with a site, try changing your browser identification in the site preferences, then press F5 to reload the page.
Note: Selecting "Identify as" means Opera will present itself as another browser, while still mentioning that it's Opera. Selecting "Mask as" completely hides Opera's identity, which is rarely necessary, but sometimes helps when visiting badly designed or broken sites.
