Ovid web applications require the following minimum browsers for OvidSP: IE 7 or later (IE 8 preferred) or Firefox 3.x or later (3.5 preferred).

The Ovid applications that are covered by these standards are: OvidSP, and Ovid LinkSolver. Ovid products require that JavaScript and Cookies are enabled.
To view PDF files in the Ovid applications you will need the Adobe Acrobat Reader. If you are experiencing difficulties utilizing our services with any other browser application, we recommend trying the above versions to correct the issue.

Ovid is focused on delivering standards compliant applications. By following common standards such as CSS and DOM, Ovid will be designing products that leverage powerful technology while ensuring that our solutions are compatible with our customer's system environments. In the future Ovid will be building toward the following standards:

• CSS 2.0
• DOM Level 3 Core
• XHTML 1.0 Transitional
• WAI-AA
• ECMAScript

Browsers
For best performance, we recommend using a browser with a fast JavaScript engine. We recommend using FireFox 3.6 or Internet Explorer 8. Internet Explorer has the slowest JavaScript engine. The same JavaScript code will often run significantly faster in Firefox than it does in Internet Explorer 6. Internet Explorer versions 6 and 7 tend to have slower JavaScript engines.

Browser Cache Settings
Caching improves page loading speed by locally storing relevant content. Our applications target a default browser configuration, particularly with regard to caching. OvidSP sends standard HTTP headers with every page that tell the browser what caching policy to use. The default browser configuration should follow what is sent in the headers. If a user overrides the caching behavior, the browser may not cache as much as it should which slows performance or may cache too long causing problems for software updates or with dynamic content.

URL Information for Firewall/Proxy Administrators
Ovid recommends that you allow users to connect to all *.ovid.com domains, to ensure uninterrupted access for users. If that is not possible, we recommend that you allow access to the following service URLs, depending on which products you subscribe to.

Ovid Resource Service URLs:

• http://ovidsp.ovid.com
• https://ovidsp.ovid.com
• http://pt.wkhealth.com
• https://pt.wkhealth.com
• gateway.ovid.com (optional SSL access)
• ssolver.ovid.com
• clinicalresource.ovid.com
• stats.ovid.com
• linksolver.ovid.com
• clineguide.ovid.com
• nursing.ovid.com

These are the only entry–point addresses that should be bookmarked and distributed to users. If you wish to bookmark OvidSP, please use ovidsp.ovid.com only. Including "tx" or "uk" could compromise your access to OvidSP.

Network traffic between Ovid and your site
All network traffic from Ovid to your site should be in response to requests which users have generated. Thus, if your site is using a stateful packet inspection (SPI) firewall, you should not have to open any ports on your firewall. Email is the exception, and you should allow TCP/25 from the address ranges listed below.

Should you use a non-SPI firewall, you will need to allow ephemeral (high numbered) TCP port access from the following IP address ranges. In order to allow Ovid the ability to expand/upgrade service without impacting connectivity, the entire range should be allowed.

• 160.109.106.x
• 160.109.107.x
• 160.109.108.x
• 160.109.109.x
• 160.109.112.x
• 160.109.113.x
• 160.109.114.x
• 160.109.98.x
• 194.66.22.128/26 (194.66.22.128 - 194.66.22.191)

To ensure proper delivery of email, customers are encouraged to explicitly whitelist our mail server IP addresses and e-mail accounts: 160.109.98.52, 160.109.107.38, 194.66.22.174, 194.66.22.175, webman@ovid.com, autorun@ovid.com, wkh-noreply@wolterskluwer.com

Note about Blacklists
As protection against spam, it's common for companies to enlist the use of "blacklists". Blacklists are lists maintained by independent organizations containing addresses of mail servers believed to be used to produce spam. Ovid’s mail server and the IP addresses used to send alerts included above, at times can inadvertently get listed on these blacklists. This happens because our alert system is quite popular by our customers and as such, produces enough emails that it can occasionally be mistaken for spam distribution. Unfortunately, for customers who haven't explicitly listed our mail server IP as valid, the blacklist causes their mail server to reject connections from our mail server.

Once Ovid learns of any inadvertent blacklisting, we have the IP removed from the blacklists, however we can't guarantee it won't end up back on them at some point in the future. To avoid problems with email delivery for users of OvidSP's AutoAlert and email functions, we strongly recommend our customers add the ranges above to be explicitly whitelisted.
