Prevent WP HTTP requests from slowing down your WordPress website and admin interface
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.
Reason may be slow external WP_HTTP requests. HTTP Requests Manager plugin 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.

Plugin tested with PHP version 5.6, 7.x and up to 8.5.
Do not confuse WP_HTTP request with HTML requests that loads page assets like js, css, image, font
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.
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.
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.

How plugin prevents slow pages containing WP_HTTP requests?
Plugin helps to prevent website slowdown by:
Sets request timeout period to 2 second. Where default is 5.
Limit number of request per page by 3. Default is unlimited.
Limit WP HTTP request if page load time is longer than 3 seconds. Default is unlimited.
Option to block all external requests or allow only requests to wordpress.org for plugin, theme and core updates.
Operation mode
Plugin has following operation modes in setting to manage WP HTTP requests. Here is what each mode does:
Only log HTTP requests — logs all non cron requests. No blocking done.
Only log HTTP requests (+ cron requests) — logs all requests including cron. No blocking done.
Smart block — logs non cron HTTP requests and blocks request using following rules. Page processing time exceeded 3 seconds.
Block external requests — all requests not matching your current domain will be blocked. No updates for WordPress core, plugins and themes. (+ Smart block features.)
Block external requests (allow WordPress.org only) — 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.)
Custom rules only work in “Smart block” mode. It will not work in “Block external requests” or “Block external requests (allow WordPress.org only)” mode.
Disable logging
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.
Load before other plugins
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.
Custom rules for “Smart Block” mode
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.
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.

No need to use define(‘WP_HTTP_BLOCK_EXTERNAL’, true); 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.
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.
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.

Frequently asked questions.
How long logs stored in database?
There is no time limit to store logs. Last 1000 logs will be stored. On average it is about 10 days of logs.
Is it possible to pause plugin and only view recorded logs?
Yes, set operation mode to “Only log HTTP requests” and check “disable logging” checkbox in “Settings” tab. With these settings new logs will not be added and you can review already existing old logs.
Does plugin removes logs and options on uninstall?
Yes it removes logs and options stored in database when you uninstall this plugin.
Which pages are recorded?
All pages with WP_HTTP requests are recorded. Slow pages without any WP_HTTP requests are not recorded.
Which remote requests are not detected?
This plugin detects only requests made using WP_HTTP class defined by WordPress. It is preferred way of doing remote requests. WordPress core and most plugins/themes use it.
Plugin will not detect requests made using other classes and functions. For example remote requests made with WordPress class WP_Http_Curl (deprecated starting from WordPress version 6.4) or PHP functions like curl_exec, fsockopen, file_get_contents are not detected by this plugin. Because they do not have hooks similar to WordPress to manage requests before making them.
Unfortunately when plugin/theme uses other functions (not WP_HTTP class) they will not be detected by this plugin.
How much performance improvement can be gained?
Performance gain on pages with WP_HTTP requests can be up to 5x. It all depends on which blocking method used and how heavyly remote requests are used by core and pugins.
Are all WordPress pages have WP_HTTP requests?
No. WP_HTTP requests are performed periodically or on certain action. When you check logged requests, there will be around 50-100 pages with requests per day. On website with 10k daily page views (human and bot traffic) it will make around 1% of all pages.
How can I feel speed improvement provided by this plugin?
You will most likely feel speed difference in admin area. Pages previously loading slowly or timing out regularly should load much faster.
