Browser Difficulties - Placing holds

We have heard of problems with the Safari browser on an Mac, and Earthlink dialup Internet. These browsers have "accelerators" similar to AOL's which store (or cache) web pages on your local PC to speed up the connection. (Please read about AOL above, especially AOL 9.0 and TopSpeed.)

A solution to this problem is to use Internet Explorer (IE) or Firefox while you are using the Library Catalog. If you prefer, you can change back to your or other browser when you are not using the Catalog.

For AOL 9.0 and Topspeed:
AOL 9.0 has a feature called TopSpeed which uses web page caching to speed up Web surfing. (This means that the AOL browser stores a copy of web pages on your local PC and uses those pages instead of going back over the Internet to get a new page display. This speeds up or accelerates your Internet connection because it reduces traffic.) We believe it is TopSpeed that is causing the problem with placing requests (holds).

If you don't want to use IE, we recommend that you turn off TopSpeed and clear the AOL browser cache. The following instructions are from the AOL help screens on TopSpeed.

For Earthlink:
We have found that if you turn off the Accelerator on the Earthlink browser, the requests (holds) problem is solved. Or, after you start up your connection with Earthlink, minimize the Earthlink browser and look for Internet Explorer on your computer.

For Safari on a Mac: You can permanently disable the cache in Safari by doing the following: 1. Go to Go/Applications on the Mac OS X toolbar. 2. From within the Applications window, double click on the Utilities icon. 3. Double click on the Terminal icon to open a Terminal window. 4. At the prompt type: rm -r ~/Library/caches/safari/ 5. Then type: touch ~/Library/caches/safari

This creates an empty file where Safari expects its cache to be and prevents it from caching any pages. We also have reports that IE and Netscape work with the Library Catalog on a Mac.

For Firefox:
You MAY need to change the cache settings in Firefox by doing the following
1. In the Location bar type: about:config
2. Press Enter. Firefox will display a list of configuration settings.
3. In the Filter box, type: cache
4. You will see the configuration settings relating to the browser cache.
5. Double-click on Browser.cache.doc_check_frequency
6. Change the setting from 3 to 1.
7. Click OK.

Browser Difficulties - Firewalls & Port 81

The following error message "Error connecting to server," is indicative of access being blocked by a firewall, proxy server, or router.
Check your firewall settings to be sure that port 81 is open. If you receive this message at home after opening your computer firewall's "port 81" (and are not using a router), contact your Internet Service Provider (ISP) and ask if they are blocking access to port 81.
If you access the internet through a router, or from work, contact your network administrator and ask that port 81 be opened on the firewall or proxy server. This is the port on which the Library Catalog and Reference Databases are accessed.

Of course, if these don't work for you, please contact the Library's webmaster at sjcwebmast@neflin.org, and we'll work together to get you the access you need.
