This document describes how to install EZproxy 5.7.44 GA for Windows. If you are updating from an older version of EZproxy, please refer to the update instructions.
EZproxy allows you to extend your databases to remote users. However, your licensing agreement with database vendors may not authorize you to provide remote access. As an implementer of remote access, it is your responsibility to verify licensing agreements and only permit remote access as authorized.
EZproxy is a completely stand-alone application. It does not require nor use any existing web server that is already installed on your server.
If you are already running a web server on the system where EZproxy is running, do not attempt to install EZproxy within directories that are used by that web server.
If you are running IIS, do not install EZproxy within the inetpub directory, and do not try to configure a web server for EZproxy within IIS Manager.

The "-m" stands for "missing file replacement" and this command can be used at any time to reconstruct any missing files without overwriting existing files that you have changed.
This command will make your server connect to an OCLC server. Your server will provide its name and IP address, then the OCLC server will attempt to verify this information. Your server will then display various messages to let you know what changes may be required for EZproxy to function properly.
Note:If you do not like the idea of your server connecting to an OCLC server, you may omit this step.If your network requires the use of a standard proxy server to connect out to the Internet, this test will fail. In this case, you will need to configure EZproxy to use your outgoing proxy server using the Proxy directive, and then you can complete the network connectivity test by finishing the installation of EZproxy and using a browser installed either on the same server or within your network to log in to the EZproxy Administration page, where you can use the Test network connectivity option. This performs a more thorough network test, including offering the option to incorporate your outgoing proxy server in the test.

Note: The options presented and how effectively they work will depend on how well you customized config.txt. As you make additional changes to config.txt, you will need to stop and restart ezproxy to make the changes take effect.

EZproxy runs on all versions of Windows 7, 2000, Windows 2003, Windows 2008, Windows XP and XP Professional.
The minimum recommended configuration for an EZproxy for Windows server is a Pentium II 400 with 256 MB of RAM. 10 MB of disk space is required for installation. Additional disk space is required to accommodate user authentication files and server log files.
This program can be executed from a non-privileged account, so please consider running it from a non-administrative account.
If your site employs a proxy server for all outgoing connections to the Internet, you will need to enter the host and port information for this proxy server into the config.txt file using the Proxy directive.
If your site is protected by a firewall, external users may be unable to connect to EZproxy unless your firewall administrator allows incoming traffic to ports 2048 and above.
