Then, we&#8217;ll dig into the difference between the two, as well as what you should use each for.<\/p><h2 class=\"wp-block-heading\">What is the Browser Cache?<\/h2><p>In general terms, &#8220;caching&#8221; something means temporarily storing it in a spot that makes for easier\/faster retrieval.<br><\/p><p>There are a lot of different ways that you can cache your WordPress website, but we&#8217;re obviously focused on one specific implementation &#8211; the <strong>browser cache<\/strong>.<br><\/p><p>Let&#8217;s start at the beginning &#8211; your site has a lot of static files that won&#8217;t change visit-to-visit. One common example is your site&#8217;s logo. You probably won&#8217;t change your logo that often, and your logo is likely the same on all or most of your site.<br><\/p><p>So let&#8217;s say a visitor views three separate pages on your site &#8211; it would be a waste to force that visitor to download the exact same logo file three times in a row, right?<br><\/p><p>The browser cache lets you avoid that situation by storing these static files on a visitor&#8217;s local computer. So with the browser cache, it would work like this instead:<\/p><ul class=\"wp-block-list\"><li><strong>First visit <\/strong>&#8211; the visitor&#8217;s browser downloads the logo file from your server and saves it locally in the browser cache.<\/li>\n\n<li><strong>Second and third visits <\/strong>&#8211; the visitor&#8217;s browser loads the logo from the visitor&#8217;s local storage (<em>the browser cache<\/em>), instead of downloading the logo again.<\/li><\/ul><p>And as a result, your website loads faster, which is a great thing.<br><\/p><p>To control how long a visitor&#8217;s browser stores certain types of files, you can set expiration dates. For example, you can tell a visitor&#8217;s browser &#8220;store all JPEG images for 4 months, but only store MP4 videos for 1 month&#8221;.<br><\/p><p>Additionally, if you <em>do<\/em> need to change a file before the expiration is up (<em>like your logo<\/em>), you can employ a technique called <a href=\"https:\/\/www.keycdn.com\/support\/what-is-cache-busting\">cache busting<\/a> to force visitors&#8217; browsers to download the most recent version of a file.<br><\/p><p>Because browser caching is a great performance tip, WP Rocket automatically adds browser caching to your WordPress site as soon as you activate the WP Rocket plugin. You can <a href=\"https:\/\/docs.wp-rocket.me\/article\/80-browser-caching\">learn more about this feature here<\/a>.<\/p><h2 class=\"wp-block-heading\">What is a Cookie?<\/h2><p>According to the dictionary, a cookie is a &#8220;small sweet cake, typically round, fl&#8221;&#8230;wait, that doesn&#8217;t sound right.<br><\/p><p>Let&#8217;s try again\u2026<br><\/p><p>A cookie is a small file that&#8217;s stored on a visitor&#8217;s device and contains data specific to a particular client. &#8220;<em>Client&#8221;, in this case, just means the device of the person who&#8217;s visiting<\/em>.<br><\/p><p>Cookies help you store useful information about a visitor, like their login information\/authentication so that they don&#8217;t have to manually log in each time, or the items in their shopping cart. Or, you can also use cookies to track and identify visitors, even between different website visits.<br><\/p><p>Cookies are only used to store text-based data, like IP addresses, session IDs, visit histories, etc. &#8211; you can&#8217;t use them to store an image, as the browser cache allows for.<br><\/p><p>Additionally, unlike a browser cache, which is a one-way transfer (<em>from the server to the local cache<\/em>), a client&#8217;s web browser will send the cookie to your web server on each visit &#8211; so the information can go from both:<\/p><ul class=\"wp-block-list\"><li>Server \u2192 client<\/li>\n\n<li>Client \u2192 server<\/li><\/ul><p>There are two types of cookies:<\/p><ul class=\"wp-block-list\"><li><strong>Persistent cookie <\/strong>&#8211; though this type of cookie has an expiration date, it stays on a visitor&#8217;s local machine while active and &#8220;persists&#8221; between visits to your website. It lets you identify a visitor even if they leave your site and come back.<\/li>\n\n<li><strong>Session cookie <\/strong>&#8211; this type of cookie is stored in memory and never saved to your visitor&#8217;s local machine. It&#8217;s active during a visit, but as soon as your visitor closes their browser, a session cookie is permanently gone.<\/li><\/ul><div id=\"om-olkrjzfbhlynbs54rv6z-holder\"><\/div>\n\t<script>(function (d, u, ac) {\n\t\t\tvar s = d.createElement('script')\n\t\t\ts.type = 'text\/javascript'\n\t\t\ts.src = 'https:\/\/a.omappapi.com\/app\/js\/api.min.js'\n\t\t\ts.async = true\n\t\t\ts.dataset.user = u\n\t\t\ts.dataset.campaign = ac\n\t\t\td.getElementsByTagName('head')[0].appendChild(s)\n\t\t})(document, 20440, 'olkrjzfbhlynbs54rv6z')<\/script><h2 class=\"wp-block-heading\">Browser Cache vs Cookies: What Are They Used For?<\/h2><p>At this point, you probably have some idea about the difference in use between the browser cache vs cookies, but let&#8217;s cover the point in a little more detail to make sure.<br><\/p><p><strong>Browser cache<\/strong> lets you store certain static files &#8211; including images, videos, CSS\/JavaScript, etc. This is a one-way relationship &#8211; those files don&#8217;t communicate back to your server once they&#8217;re stored. Additionally, the browser cache doesn&#8217;t identify specific users &#8211; it treats all users the same.<br><\/p><p>The browser cache helps you <strong>speed up your site <\/strong>and lessen the load on your server &#8211; that&#8217;s all it&#8217;s used for.<br><\/p><p><strong>Cookies<\/strong> are small text-based files that let you track, identify, or otherwise store information that&#8217;s unique to each visitor. This is a two-way relationship, where your server is able to read the information from the cookie.<br><\/p><p>Cookies help you provide a better user experience, like recognizing that a user is logged-in or identifying a visitor to show them the items in their shopping cart at an eCommerce store.<br><\/p><p>Or, cookies can help you track and identify specific visitors, like setting a cookie so that you don&#8217;t display an email opt-in popup after a visitor has already subscribed to your email list.<br><\/p><p>Finally, you can even use cookies to help with <em>off-site<\/em> functionality. For example, setting a retargeting cookie so that you can display ads to your site&#8217;s visitors even when they&#8217;re on other sites.<\/p><div id=\"om-ulrdquoprwqcywqbbgci-holder\"><\/div>\n\t<script>(function (d, u, ac) {\n\t\t\tvar s = d.createElement('script')\n\t\t\ts.type = 'text\/javascript'\n\t\t\ts.src = 'https:\/\/a.omappapi.com\/app\/js\/api.min.js'\n\t\t\ts.async = true\n\t\t\ts.dataset.user = u\n\t\t\ts.dataset.campaign = ac\n\t\t\td.getElementsByTagName('head')[0].appendChild(s)\n\t\t})(document, 20440, 'ulrdquoprwqcywqbbgci')<\/script><h2 class=\"wp-block-heading\">Browser Cache and Cookies in WP Rocket<\/h2><p>If you&#8217;re a WP Rocket user, WP Rocket gives you ways to work with both the browser cache and cookies on your WordPress site.<br><\/p><p>First, as you learned above, WP Rocket automatically activates browser caching as soon as you activate the plugin. So if you&#8217;re using WP Rocket, your WordPress site is already benefiting from the performance-boosting effects of browser caching.<br><\/p><p>Second, WP Rocket lets you change your site&#8217;s page caching behavior based on cookies.
