Thank you. Nevertheless I spotted another issue now. Crawled pages remain cached until a new post is published, then ALL of them get invalidated! Why is that? I have visited the Purge tab on the LiteSpeed Cache Settings section, and at “Auto Purge Rules For Publish/Update” I have the following checked: * Front Page Home PagePagesAll pages with Recent Posts Widget (which I have none since I do not use the Resent Posts Widget)Author archivePost type archiveMonthly archiveTerm archive (include category, tag, and tax) * Is there something wrong? why to invalidate all individual pages if a new post is published? * Looking forward to your feedback. * Best, Byron * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[LiteSpeed Cache] Crawler does not seem to cache pages](https://wordpress.org/support/topic/crawler-does-not-seem-to-cache-pages/) * Thread Starter [kioub](https://wordpress.org/support/users/kioub/) * (@kioub) * [2 years, 6 months ago](https://wordpress.org/support/topic/crawler-does-not-seem-to-cache-pages/#post-17165996) * No, that is exactly the issue, as I described it in my initial message.

I paused CF on both sites so requests/responses targeted the origin server directly and tested again, but with no luck. The behavior/results were the same, although Remote Address header shown the origin server IP (rather than a CF IP). * Furthermore I have asked our hosting provider to send the vhost conf files over and I can validate that they are the same (apart from the respective hostnames of course). * Last but not least, It seems that this issue is present only on non-static pages of the sites. On consequent refreshes of static pages e.g. * [https://systemcodegeeks.com/readme.html](https://systemcodegeeks.com/readme.html) * HTTP 304 is returned. * I am looking forward to your feedback. * Best regards, Byron * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[LiteSpeed Cache] Failed to push to LiteSpeed IAPI server: “Too many errors while fetching image s](https://wordpress.org/support/topic/failed-to-push-to-litespeed-iapi-server-too-many-errors-while-fetching-image-s/) * Thread Starter [kioub](https://wordpress.org/support/users/kioub/) * (@kioub) * [8 years, 1 month ago](https://wordpress.org/support/topic/failed-to-push-to-litespeed-iapi-server-too-many-errors-while-fetching-image-s/#post-10096844) * Hello, * I was able to pull the images.

After I select the “Destroy All Optimization Data” button and the “Destroy It!” button to the image server confirmation message, a new tab opens, to “[https://wp.api.litespeedtech.com/go?data=…”](https://wp.api.litespeedtech.com/go?data=…”); but I get timeout errors (HTTP 524) every time this happens. * Below is the result I see. * ****** * Client callback failed: Error 524 Ray ID: 3fb234b20fa995bc • 2018-03-13 23:17: 41 UTC * A timeout occurred * You * **Browser** * Working Ashburn * **Cloudflare** * Working [http://www.javacodegeeks.com](http://www.javacodegeeks.com) * **Host** * Error * What happened?

Additional troubleshooting information here. * ***** * As a result, I returned to Level 1 (I was at Level 5), I can send images for optimization again, but all of them get stack and never get pulled. * To my opinion this is a major bug that you must fix ASAP. * I am paying for a 2 CPU core licence for LiteSpeed and I expect way better level of support from you. * Looking forward to your feedback, and prompt actions. * Best regards, Byron * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[LiteSpeed Cache] Requests optimized but not pulled](https://wordpress.org/support/topic/requests-optimized-but-not-pulled-2/) * Thread Starter [kioub](https://wordpress.org/support/users/kioub/) * (@kioub) * [8 years, 5 months ago](https://wordpress.org/support/topic/requests-optimized-but-not-pulled-2/#post-9773066) * Thank you for the clarification of the cause of this error – although I do not fully understand what “repeatedly taken” really means. * Nevertheless I – along with all the users experiencing the same issue – just want this fixed!

Using this option a site does not have to be SSL enabled. Pages from my site are served by CloudFlare over HTTPS while they communicate with the origin server through plain HTTP. * I looked at LiteSpeed plugin code and discovered that you are making this call when someone requests a key from your image server (litespeed-cache/admin/admin- api.class.php, function _request_key() line 201) * `$json = $this->_post( self::IAPI_ACTION_REQUEST_KEY, home_url() ) ;` * Unfortunately the `home_url()` call returns the plain HTTP version of my site’s homepage since the server is not HTTPS enabled. Nevertheless if your image server tries to contact my site’s homepage (any any page for that matter) over plain HTTP, CloudFlare redirects them to the HTTPS version of it automatically. * I managed to get over this issue by replacing the call to `home_url()` with ` home_url('/','https')` but this is only to validate my point. * I would really like you to apply a patch to one of the following updates of the plugin so as to address this issue and be able to support this kind of setup since a vast amount of sites utilize CloudFlare’s Flexible SSL feature. * Looking forward to your feedback. * Best regards, Byron Viewing 15 replies - 1 through 15 (of 29 total) 1 [2](https://wordpress.org/support/users/kioub/replies/page/2/?output_format=md) [→](https://wordpress.org/support/users/kioub/replies/page/2/?output_format=md)
