What is the QUIC.cloud Bot (qcbot)?¶
The QUIC.cloud Bot, or qcbot, functions as a web crawler for all QUIC.cloud Online Services which require data to be fetched from and returned to your website. For example, qcbot retrieves images from your site for Image Optimization, and notifies your site when the updated images are ready to be pulled.
Important
qcbot is used for all QUIC.cloud services except for the CDN. To take full advantage of our services, qcbot may need to make multiple access requests to your website. The QUIC.cloud bot makes all such requests through a QUIC.cloud IP, so be sure to add these IPs to your allowlist.
It is crucial that qcbot has unrestricted and unfiltered access for the optimal performance of all QUIC.cloud services on your site.
Recognizing QUIC.cloud Bot¶
The QUIC.cloud bot will always have a user-agent containing qcbot, as in the following examples: Mobile:
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; qcbot/1.0; +http://quic.cloud/bot.html) Chrome/112.0.0.0 Safari/537.36
Desktop:
Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Mobile Safari/537.36 (compatible; qcbot/1.0; +http://quic.cloud/bot.html)
Controlling the QUIC.cloud Bot¶
The number of requests made by the QUIC.cloud bot to your website depends on the specific Online Services you use. For instance, the Image Optimization service will request image files on your site, while UCSS, CCSS, and VPI will access all pages.
All requests from qcbot are essential for optimizing your website.
There should be no reason to reduce the number of requests qcbot makes to your site. However, if you wish to do so, the only way is to review the QUIC.cloud services you have enabled in the LiteSpeed Cache plugin, and disable any unnecessary features.
