Frequently Asked Questions – System Requirements


In order to provide the best possible HeinOnline research experience, the information technology staff at William S. Hein & Co., Inc. has dedicated considerable time and resources to develop a system that is both fault tolerant and robust. To prevent system failures and to ensure seamless database access during periods of server downtime, HeinOnline uses a multitude of technologies which include hardware and internet connection redundancies, DoS protection, load balancing, and automatic failovers among multiple servers. In order to ensure that HeinOnline access is not interrupted due to routine server maintenance or unexpected failovers, it is vital that all customers configure their systems with the proper HeinOnline domain name and standard DNS practices. Proper configuration will ensure that these performance enhancements and redundancies are not circumvented.

At this time, we recommend and officially support access to HeinOnline via domain name (heinonline.org).  Locking a proxy server or web portal onto a specific IP address circumvents many of the systems we have put in place and could potentially cause interruptions in HeinOnline access.  Caching should also be disabled on any proxy server utilized to access HeinOnline.  We publish a short TTL on our DNS A-Records and it is important not to hold onto these records for longer than the published 15 seconds.

While we do not recommend utilizing IP addresses in proxy configurations, the following is provided for informational purposes only:
