EZproxy is server based software provided by the Library that is used to access our online resources and online subscriptions for off campus users. This service is especially useful if you are not using your own computer (off-campus libraries, Internet cafes, etc)
Important FAQ's when using EZproxy
- Only users who have a secondary (also called phage or dmz ) username and password are able to use EZproxy.
This password must be created on campus. Visit the Secondary Password Creation and Forgotten Password Site to set a secondary password.
- you must access the journals, databases and ebooks through the library's web site. The links there have the correct url's that use ezproxy.
If you are not using the library website to access the journals, please see the EZProxy Bookmarklet hack.
For solutions to common EZProxy access problems, see the EZproxy - Remote Access Solution FAQ.
Help with remote access set-up:
*Some resources need a password and those passwords can only be viewed on campus. Also, the resource must be entered in our proxy database.
When working from off-campus, you can utilize VPN to gain access to on campus resources, such as: compute servers, file servers and printers. When using the CSHL VPN client software, your remote computer will appear as if it were on-campus. This includes having a CSHL campus IP address.
Thus by using VPN to connect to the CSHL campus, you internet traffic will be originating from the CSHL campus and you should have full access to journals, databases and other commercial content.
A VPN client for your PC or MAC must be obtained from the Information Technology department. Please call the IT helpdesk at x8390 to get set-up for access.
Journal Access Off CSHL Campus
CSHL members my access our journal subscriptions, using VPN or EZProxy. The CSHL Journal Holding list from the CSHL Library website and BrowZine, will prefix our EZProxy address onto the journal resource when you are off campus.
What if I'm not starting from the Library website, when I am off campus?
In most cases when accessing an article from an email alert, RSS feed or link from other website, the link will not have the CSHL EZProxy address baked in to the publishers URL link.
Drag this button to your bookmarks toolbar → Reload via EZproxy
Adding the above button to your web browser bookmark toolbar only needs to be done once. Naturally, you need to make sure the bookmark toolbar is visible
When your are at publisher website that does not recognize you from CSHL, the above bookmarklet will rewrite the URL in your browser's address bar, so that you get authenticated and access the journal through the CSHL network.
If you have never used the EZProxy Bookmarklet before, check out this video from UCFS Library.
You can also manually prefix our EZProxy address onto a journal URL:

EZproxy is browser independent, i.e., any browser (Other than AOL) should work with EZproxy. A current browser should be more reliable.
EZproxy should require no configuration on the user's part. When you click on a link to an online library resource, EZproxy checks whether your computer is on campus or off.
- If you are on campus, you should bypass EZproxy and be sent directly to the resource.
- If you are off campus, you will be required to login with your windows username and your secondary (also called your phage or dmz) password. This password must be created on campus. Click here to set a secondary password.
If you want to access the article from off campus, please add this string:
in front of the URL for the article. For example, if the URL is:
and you want to access the article from off campus, your URL should be:
Some corporate, agency, or institutional, dial-up, cable, or broadband connections may automatically configure browsers so their own proxy server is used. It's possible these automatic settings, if they exist, could interfere with the use of EZproxy. If these networks have a firewall or preset internet security settings they could interfere with EZproxy.
ISPs that use proprietary versions of browsers, such as AOL or Prodigy, can cause some problems for EZproxy. A simple workaround is to connect to the provider, minimize your session and use your own copy of Netscape or Internet Explorer for accessing the library?s resources instead of their browser.
Another common problem is that during set up of dial-up, cable, or broadband connections, certain browser settings get configured according to THEIR preferences. This is another reason to minimize your session and use your own copy of Netscape or Internet explorer when using library resources.
Both EZproxy and certain databases send "cookies" when you connect to them to verify, during your session, that you are an authorized user.
If your browser reported an error receiving a "cookie" and it may be currently set to disallow cookies. EZproxy requires that your browser is set to ENABLE COOKIES.
You will get a Hostname Error page when you attempt to access a database or journal that has not yet been set up for use by EZproxy.
Database vendors often change domain names, or pull content from new computer hosts without ever informing libraries. Thus, when a hostname error occurs, EZproxy's configuration must be updated to include the new host for proxying.
To expedite correction of this error, please send the following information to libraryhelp (or call x6872):
- the name of the resource you were trying to access
- the computer hostname line listed on the error page
EZproxy delivers error pages to users for certain common problems. These will usually have the libraries' header and information relevant to explaining the problem and solution.
There are a variety of common errors that occur during general surfing of the Internet. When they occur, the web server (or web browser) sends an error page for you to view - usually without a lot of explanation. These may or may not be related to EZproxy. Two common Internet errors are:
- 404 Errors (Page not Found)
- "Server not Found or DNS Error"
Users may get these errors for a variety of reasons.
- An incorrect URL, outdated link or a missing page
- Some aspect of your network is down or very busy
Whenever you get an error page, especially one that doesn't come from EZproxy, it is important you note what the error page says, the URL you were trying to access (and from where) and other relevant information.
Some products require a particular browser or version. In particular, an increasing number of websites are no longer capable of being viewed by older browsers, such as Netscape 4.7 or 4.8 (WebSpirs is an example of one of those sites).
The various database vendors use a variety of programming methods on their database web sites. Some of these methods can make it hard for our server to keep passing information between you and the site. If certain links or other aspects of the site aren't functioning, there are a few primary possibilities:
- EZproxy's configuration for the database needs to be adjusted
If these features function when accessing the resource from on campus (which doesn't use EZproxy), then EZproxy's configuration may have to be adjusted to adapt to the database's particular method
- Problem is with vendor's site
Like any information technology, there are often problems on the vendor's end that lead to problems with the database. These problems are generally resolved fairly quickly once the vendor is aware of them.
- Problem is with your browser's ability to handle site's programming
- Certain content or features are not part of the library's subscription
In a few databases, the library's subscription does not provide access to all features or content on a site. In this case, you may get an error message or login screen - though it may also be that what appear to be links to those features are simply not active.
A problem can occur with Microsoft Internet Explorer 5 (or higher) interfacing with Adobe Acrobat 4. Please try the following:
- Open Adobe Acrobat (from your Start --> Program menu)
- Click on File --> Preferences --> General
- Uncheck the box next to Web Browser Integration
Some full text journals are freely available to anyone on the Internet, either for a limited time or permanently. These titles are listed on the electronic journal pages, but they do not require a login.
14. Why can't I use The AOL Browser for off campus access?
If you are currently using an AOL browser and want to successfully access the Library's resources from off-campus, please download Netscape Navigator, Mozilla or Microsoft Internet Explorer. Minimize AOL and open one of these browsers to access the resources at CSHL.
If you see a "Page Not Found" message after you log in. Click on "Back" and try the link again. It should work the second time.
This is not an access problem. You can call the Library Reference Desk at x6872 for assistance.
