End of support for EZproxy on Solaris platform
OCLC ended support for EZproxy on the Solaris 10 (x86) platform on October 31, 2018. We no longer provide software for this platform. We will continue to provide Linux and Windows versions of the software. Customers using EZproxy on Solaris should plan to move their installation of EZproxy to Linux or Windows. If you have questions about this change, please reach out to Customer Support (

When you are ready to install EZproxy, it is best to have your subscription confirmed and your license key, called a WSKey, ready to install. If you have not already received a quote and completed an order form, please visit Ordering EZproxy to take these steps. After you have placed your order, you can Request a WSKey. If you have any additional questions about the order, WSKey, or installation process, please email  

If you obtained a WSKey when you updated to any V6.x, you can use the same WSKey to upgrade to any new release of EZproxy.
