Cache memory
A cache is a memory location that is
used to store data temporarily. If you
have tried to access or have accessed
confidential information requiring
passwords, empty the cache after
each use. The information or services
you have accessed is stored in the
cache.
To empty the cache, while browsing,
select Options > Other options >
Clear the cache; in the standby
mode, select Menu > Web > Clear
the cache.
Browser security
Security features may be required
for some services, such as online
banking or shopping. For such
connections you need security
certificates and possibly a security
module, which may be available on
your SIM card. For more information,
contact your service provider.
Security module
The security module improves
security services for applications
requiring a browser connection, and
allows you to use a digital signature.
The security module may contain
certificates as well as private and
public keys. The certificates are
saved in the security module by the
service provider.
