To configure your proxy settings in MATLAB:
1) Launch MATLAB
2) Select the "Home" tab
3) Select "Preferences"
4) Select "Web"
5) Check the box labeled "Use a proxy server to connect to the Internet"
6) Fill in your proxy information
7) If authentication is necessary, check the box labeled "Use a proxy with authentication" and fill in the appropriate information
8) Use the "Test connection" button to verify that the information entered was correct
NOTE: Only R2008b and newer has the ability to test the proxy connection and enter authentication information.

Joe T asks:
how can you adjust the encryption method?
you can see all methods with
methods(com.mathworks.services.Prefs)
but these do not seem to take effect immediately. Instead you could use the API:
com.mathworks.mlwidgets.html.HTMLPrefs.setUseProxy(true)
com.mathworks.mlwidgets.html.HTMLPrefs.setProxyHost('127.0.0.1') % or whatever
com.mathworks.mlwidgets.html.HTMLPrefs.setProxyPort('8080')
com.mathworks.mlwidgets.html.HTMLPrefs.setProxyUsername('YOURUSER')
com.mathworks.mlwidgets.html.HTMLPrefs.setProxyPassword('password123')
