125 Internet
To set up the Internet program to use a proxy server:
1. On the Tools
menu, select Proxy server settings.
2. Select the Internet service provider or corporate network you want to set
up the proxy server for in the Service provider line.
3. Select ‘HTTP’ in the Protocol line and put a tick in the Use proxy server
box. (HTTP is the protocol for transferring web pages.)
4. In the Proxy server line, enter the location of the proxy web server, then
enter the port number you will use to connect to it. Select OK.
Note! Note that the port number does not refer to the actual Serial port on
your machine, but is a type of ‘channel’ that machines agree to use for
communications on the Internet.
Tip! Web servers often use 80 as the port number. If you do not know the port
number, it is recommended you try using this. If this number does not work,
you should contact the proxy machine’s administrator.
Setting up proxy server exceptions
If you have set up the Internet program to use a proxy server for web pages,
you can still specify sites where the Internet program will not use that proxy
server but instead access the site directly.
To specify sites where the Internet program will not use that proxy server:
1. On the Tools
menu, select Proxy server settings.
2. Select the Internet service provider you want to set up the proxy server for
in the Service provider line.
3. Tap the Exceptions
button.
4. Select the Add and Remove
buttons to add and remove proxy server
exceptions, e.g. ‘www.ericsson.com’, to the list. Select OK.
The Internet program can store copies of web pages you have viewed during
any one session to enable you to return to them quickly, and even view them
when you are not connected to the web. You can vary the size of this cache of
pages according to the amount of memory you have free.
To change the size of the cache:
• Select General preferences on the Tools menu, tap on the Other page and
enter a new number in the Maximum cache size line.
Note! Note that this is not an absolute maximum: for short periods, the
Internet program may use slightly more than the amount of memory you
specify as a maximum cache size. It will return to using a level within the limit
as quickly as possible.
Note! It is best to keep the maximum cache size significantly below the
amount of free memory you have at present. This will prevent difficulties
owing to a shortage of memory occurring when the cache is full.
