KYVL QuickSearch



Troubleshooting

Bypassing proxy or cache

If your organization/library/school uses a proxy server or an internet caching system, such as Cacheflow, KYVL databases will not authenticate properly. Because of the dynamic nature of the databases, it is important that member institutions allow these sites to bypass the proxy or caching system to allow the end user to achieve direct communication with these databases and not a cached version of the site. The sites become very difficult to use if they are not passed through and can return wrong and irrelevant results to your users, or impede access completely.

It is important to add KYVL resources to your "pass-through" list or filter. Consult the documentation of your proxy/caching device for the specific instructions.

A list of domains to whitelist is found below.

EBSCO domains to whitelist

Libraries and districts using firewalls, proxy servers, caching servers, filtering software and other security features will need to whitelist certain domains to provide network users full access (incoming and outgoing traffic) to KYVL's EBSCOhost and affiliated products.

EBSCO maintains a complete listing of domains for firewalls, proxy servers and whitelists here.

Allow access to the following ports for TCP, specified by service:

Port Service
80 EBSCO's databases and EBSCOhost Integrated Search
210 EBSCOhost via z39.50
443 EBSCOhost via HTTPS
554 and 1755 Audio Streams available from EBSCO interfaces.
If you cannot view videos, you may need to open all ports for http://epmedia.ebscohost.com
8080 and 8443 May be needed to support Shibboleth

To prevent any issues with access, please do not filter or cache the following domains:
