<h4>Prevent WP HTTP requests from slowing down your WordPress website and admin interface</h4>
<p>Do you have a slow WordPress admin that takes longer than usual to load? Sometime longer than 5 seconds to load admin or login pages. In rare occasions WordPress may even timeout and show 504 page.</p>
<p>Reason may be slow external WP_HTTP requests. <a href="https://veppa.com/http-requests-manager/" rel="nofollow ugc">HTTP Requests Manager plugin</a> will log all WP HTTP requests with time taken to complete for each request. If there are multiple requests per page they will be color grouped.</p>

<p>Plugin tested with PHP version 5.6, 7.x and up to 8.4.</p>
<h4>Do not confuse WP_HTTP request with HTML requests that loads page assets like js, css, image, font</h4>
<p>Plugin only detects and manages requests made using WP_Http class. Which is default method used and advised by WordPress for getting remote data and updates.</p>
<p>Plugin will not detect any requests made by other WordPress classes like WP_Http_Curl or PHP functions like curl_exec, fsockopen, file_get_contents etc.</p>
<p>Do not confuse it with HTML requests (loading assets like css, js, image) done by HTML page. WP_Http requests are performed only inside PHP files and not visible in web browser.</p>

<h4>How plugin prevents slow pages containing WP_HTTP requests?</h4>
<p>Plugin helps to prevent website slowdown by:</p>
<ul>
<li>Sets request timeout period to 2 second. Where default is 5. </li>
<li>Limit number of request per page by 3. Default is unlimited.</li>
<li>Limit WP HTTP request if page load time is longer than 3 seconds. Default is unlimited.</li>
<li>Option to block all external requests or allow only requests to wordpress.org for plugin, theme and core updates.</li>
</ul>
<h4>Operation mode</h4>
<p>Plugin has following operation modes in setting to manage WP HTTP requests. Here is what each mode does:</p>
<ul>
<li><strong>Only log HTTP requests</strong> — logs all non cron requests. No blocking done.</li>
<li><strong>Only log HTTP requests (+ cron requests)</strong> — logs all requests including cron. No blocking done.</li>
<li><strong>Smart block</strong> — logs non cron HTTP requests and blocks request using following rules.
<ol>
<li>Page processing time exceeded 3 seconds.</li>
<li>Number of request for single page reached 3.</li>
<li>Sets timeout for each request to 2 second.</li>
<li>Sets number of redirects for request to 1.</li>
<li>Apply custom rules for “Smart block” defined in settings. </li>
<li>Prevent some built in requests: happy browser, maybe update, self pings, do_enclose.</li>
<li>Skip some limitations listed above for: file downloads (plugin, theme, other), requests inside cron jobs.</li>
</ol>
</li>
<li><strong>Block external requests</strong> — all requests not matching your current domain will be blocked. No updates for WordPress core, plugins and themes. (+ Smart block features.)</li>
<li><strong>Block external requests (allow WordPress.org only)</strong> — all requests not matching your current domain and wordpress.org will be blocked. Allows updates for WordPress core, plugins and themes coming from wordpress.org website. (+ Smart block features.)</li>
</ul>
<p><strong>Custom rules</strong> only work in “Smart block” mode. It will not work in “Block external requests” or “Block external requests (allow WordPress.org only)” mode.</p>
<h4>Disable logging</h4>
<p>After using plugin for some time and knowing which requests are performed you can disable logging. Operation mode will remain unchanged. Request blocking will remain in tact. No new logs will be recorded. You can analyze old logs, they will not be deleted.</p>
<h4>Load before other plugins</h4>
<p>In order to catch more requests you can enable “Load before other plugins” option. It uses Must-Use plugin feature and load before other regular plugins. This way you will make sure to detect all WP_HTTP requests by other plugins.</p>
<h4>Custom rules for “Smart Block” mode</h4>
<p>Allow or block some requests based on domain, plugin or all. Choose on which page type rule will be applied. For example you can block requests in frontend while allowing in other pages.</p>
<p>Finally you can define action as block or allow for custom rule. For example you can make sure that some plugin will always be allowed to send WP_HTTP request. This can be SEO or mail plugin that uses remote API for functioning.</p>

<h4>Use cases</h4>
<ul>
<li>Check if WordPress communication to remote APIs works without any problem. — <a href="https://veppa.com/debug-wp_http/" rel="nofollow ugc">Check how easy it is to debug WP_HTTP requests <span aria-hidden="true" class="wp-exclude-emoji">→</span></a> </li>
<li>Identify if your website slow because of WP_HTTP requests. Average page load time, average request time and average number of requests per page shown as summary at the top of reports. </li>
<li>Block all external request on development or localhost website. All updates will be blocked. You switch off blocking when you want to perform Core, Plugin, Theme updates. No need to use <strong>define(‘WP_HTTP_BLOCK_EXTERNAL’, true);</strong> in your wp-config.php. Plugin will prevent requests automatically when you choose “Block external requests” or “Block external requests (allow WordPress.org only)” operation mode. </li>
<li>Block non WordPress request. No data will be sent to third parties. They are usually loading other website news, plugin/theme promotions, advertisements, sending usage statistics etc. </li>
<li>Prevent your website from timeout. By blocking all requests if page generation time exceeds 3 seconds. Kill slow HTTP request with small timeout of 2 second. Slow request can be because of temporary network problem or remote website can be too busy to respond on time. Slow request is not your fault so your website should not suffer from it. — <a href="https://veppa.com/optimize-wp-http-requests/" rel="nofollow ugc">Learn how WP_HTTP Optimization works <span aria-hidden="true" class="wp-exclude-emoji">→</span></a></li>

HTTP Requests Manager


Most of the delays in WP admin are http phone home calls.



This plugin solves exactly that, and you can see who the worst culprits are, too!



This belongs on every WordPress site by default.



Thanks for your amazing work @veppa !



(Small request: can we have a setting to tweak that max page loading time down from 3 seconds? Perhaps options for 3.0, 2.5, 2.0, 1.5, 1.0, 0.5, maybe 1.5 as the default?)
