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"
- Search using your default search engine for "opera"
When you enter a single word in Opera's address field, followed by a forward slash (for example "opera/"), Opera will:
- Look for a computer in your local network called "http://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 ⌘+Enter.
Proxy servers ¶
A proxy server is a computer that can, for example
- Store local copies of webpages so that a group of people (such as employees or subscribers) can get quick access to often-visited webpages
- Act as an interpreter between your browser and a special service
- Alter or monitor information exchange
- Speed up internet communication
To change your proxy server, go to, 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 184.108.40.206)
- 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.
You can specify whether you want the proxy used even for local servers by checking the "Use proxy for local servers" checkbox.
To access certain sites without going through the proxy, you can enter a list of web addresses to exclude. See: Bypassing proxy servers: Exception List below.
If your internet provider requires automatic proxy, please enter the web address provided by your ISP.
Adding proxy servers manually ¶
Your service provider or network administrator should have provided you with the necessary server names and port numbers. If not, please contact the appropriate party and ask them for this information.
These are the supported proxy protocols:
- HTTP: for HTTP servers (ordinary websites)
- HTTPS: for secure documents (use only when behind a firewall)
- FTP: for FTP files
- Gopher: required if you want to access gopher servers
- WAIS: required if you want to access WAIS servers
- Go to , and click .
- Tick the checkboxes for the protocols you want to use a proxy for, and enter the proxy server hostname or IP address in the text field to the right of the protocol name (HTTP, HTTPS...). To the right of the protocols there is a box available for the port number.
[v] HTTP [ proxy.proxyexample.com ] Port 
[v] HTTP [ 220.127.116.11 ] Port 
Bypassing proxy servers: Exception List ¶
You can specify which servers should be accessed directly and not through the proxy by adding them to an exception list. For example, you may want to do this if a server is so close that the proxy would be a bottleneck even if it had the document stored locally. Just click thebutton, select the option "Use proxy for all servers except those on the list", and add one server or host per line, like this:
This tells Opera that the *.opera.no domain and the www.opera.com server should be accessed directly and not routed through the proxy. As the example shows, wildcards can be used. You can also separate entries by using a comma or semicolon instead of putting each one on a separate line.
Conversely, you can set up a whitelist of servers that should be routed through the proxy, by selecting the option "Only use proxy for servers on the list". Normal traffic will not use the proxy.
Automatic proxy configuration ¶
For automatic proxy configuration, click the radio button for "Use automatic proxy configuration" and enter the address (URL) to the automatic proxy configuration script in this field.
Encode international web addresses with UTF-8 ¶
Some servers may prefer that Opera encodes the address in local character encoding (like latin-1) instead of the recommended UTF-8 encoding. Set these preferences at.
|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|
Max connections to a server ¶
It is recommended to keep the default setting of 16, but you can try changing the maximum number of connections to a single server if you are experiencing problems with browsing speed.
Max total connections ¶
It is recommended to keep the default setting of 64, but you can try changing the maximum number of connections to all servers if you are experiencing problems with browsing speed.
