FirstGlance in Jmol: Servers
FirstGlance in Jmol is available from the servers listed below. Users in North America can expect bioinformatics.org/firstglance to take you to an optimal server.

- bioinformatics.org/firstglance: This is the home URL for FirstGlance, and should be used by all links from users in North America. It will redirect users to an optimal server. (In October, 2005, the bioinformatics.org server was too slow for satisfactory use.)
- firstglance.bioinformatics.org: This domain is not recommended for links; use bioinformatics.org/firstglance for links. In October, 2005, this domain goes to a temporary server, much faster than bioinformatics.org, kindly provided by Jeff Bizzaro at the University of Massachusetts, Lowell.
- Additional servers on various continents are planned. Suggestions welcome to emartz@microbio.umass.edu.

If you have a fast Internet connection (DSL, Cable, or T1) the Gallery speed-test molecule should appear in one minute or less on the first try (about 30 seconds under optimal conditions). If it takes substantially more than one minute to display 1d66.pdb, look for a faster server. Slow results can be due to the speed of your computer, the connection of your computer to the Internet, the speed of the Internet between your computer and the server, the connection of the server to the Internet, or loading of the server. Which server is fastest may change with time.
After the molecule is displayed for the first time, subsequent displays of any molecule will be much faster. This is because:

1. The Jmol java applet is in the local java cache.
2. The HTML/javascript is in the local browser cache.
3. The java code has already been interpreted.

Clearing the caches:

- Windows Java cache: Open the Java Control Panel from the Windows Control Panel (available from the Start menu, may be under Settings). Under Temporary Internet Files, use Delete Files to delete applets.
- Browser cache:
  - Internet Explorer: Tools, Internet Options, General Tab, Section Temporary Internet Files, Delete Files.
  - Firefox: Tools, Options, Privacy, Cache, Clear.
  - Netscape 4-7 or Mozilla: Edit, Preferences, Advanced, Cache, Clear Cache, OK.
