Remote site settings
Salesforce allows you to access external website resources from a Salesforce application for your organization. You can access these external websites through Visualforce pages, Apex Callout, and via XmlHttpRequest calls. To avoid accessing malicious websites from Salesforce.com, the website first needs to be registered with remote site settings. Once the site is registered, it can be used within Salesforce.com.
To register a new site, follow these steps:
Navigate to Setup | Administer | Security Controls | Remote Site Settings.
Click on the Remote Site Edit button to add a new site:
It will redirect you to a new page where you have to fill in the required information to register the new site. The description of various fields is as follows:
