6. Troubleshooting web sites
6.1 Troubleshooting a web site without the Nokia 9120 Communicator
Newer versions of the Nokia 9210 SDK (Software Development Kit) for the Symbian Platform also contain the web
browser. You can run the browser in the Nokia 9210 emulator on a desktop PC. This way, you can see exactly how the
page is going to look on a Nokia 9210 Communicator. However, please bear in mind, that at the time of writing, some
features of the browser may still be undergoing changes. If you are using a beta version of the SDK, it also has a beta
version of the web browser. The SDK is freely available from Forum Nokia (http://www.forum.nokia.com/).
Connecting to the Internet with the emulator is possible over a dedicated PPP connection or by using a modem
connected to the desktop PC. You can get instructions for how to connect to the Internet from Forum Nokia. Search
for EPOC SDK Internet Connectivity FAQ.
6.2 What can I do, when...
6.2.1 I see a HTML page that tells me that I should upgrade my browser, or have a wrong browser
This is usually caused by the web site checking for the HTTP User-Agent header and making decisions based on it. Web
users have traditionally been using two major flavours of web browsers, and many sites still have a start page that
filters out the users of all other browsers. This can be fixed by either removing this check altogether or adding support
for the Nokia 9210 Communicator web browser.
6.2.2 Secure connections will not succeed
If you see a HTML page that tells you that secure connections are not possible, the most likely reason is that the site
checks the User-Agent header and does not even start secure connection handshake because it does not recognise the
Nokia 9210 Communicator web browser. The Nokia 9210 Communicator should be added to the list of accepted web
browsers.
