<div id="body1499753333227"><p id="en-us_topic_0045853689__p23599622102642">Some rogue websites may steal links from other websites to enrich their content without any costs. Link stealing hurts the interests of the original websites and it is also a strain on their servers. URL validation is designed to address this issue.</p>

<p id="en-us_topic_0045853689__p45291699">In HTTP, the <strong id="en-us_topic_0045853689__b933521718102">Referer</strong> field allows websites and web servers to identify where people are visiting them from. URL validation of OBS utilizes this <strong id="en-us_topic_0045853689__b131551015122">Referer</strong> field. The idea is that once you find that a request to your resource is not originated from an authorized source, you can have the request blocked or redirected to a specific web page. This way, OBS prevents unauthorized access to data stored in buckets.</p>

<p id="en-us_topic_0045853689__p4972115">Such authorization is controlled using both whitelists and blacklists.</p>
