A small issue with Drupal

Drupal usesdrupal_http_requestFunction to obtain system updates or RSS information from other websites. Ifdrupal_http_requestFunction access fails.drupal_http_request_failsSet variableTRUE. For subsequent access, you must firstsystem_check_http_requestTo confirm that the system does supportdrupal_http_request. Whilesystem_check_http_requestYesdrupal_http_requestVisit your site.

This system has no problems, but if nginx + PHP-CGI (1 child) mode is used in the background, because there is only one PHP-CGI instance, the PHP running in it cannot access its own site. At this time, PHP-CGI is already busy. The gateway time out error occurs.

This issue has no impact on common users. Only when/adminAnd/admin/report/statusErrors may occur because these two webpages callsystem_check_http_request, Ifdrupal_http_request_failsTrue.

Solution,

1. Modifysystem.moduleFilesystem_check_http_requestSo that it can detect websites like Google that will not be dropped.drupal_http_request.
2. Use two PHP-CGI children
3. Modify the configuration of the Web server (nginx). If the access/request is initiated from a local machine, it is automatically switched to a static file.

Modifying system modules will always cause a variety of troubles. Two PHP-CGI instances consume a large amount of memory. Although the latter solution is ugly, it is easier to use, we will not worry about Drupal upgrade in the future.
