At this time, it is not possible to activate GZIP compression for dynamic HTML content on the Platform.sh service. This limitation arises due to the inherent vulnerabilities associated with this method, particularly its susceptibility to certain types of attacks known as CRIME and BREACH. These attacks exploit weaknesses in the way data is compressed and encrypted, potentially leading to serious security breaches. As a result, the decision has been made to disable this feature to protect users and their data from potential threats.
Despite this restriction on Platform.sh, there is a viable alternative for enabling GZIP compression through the use of Fastly, a powerful content delivery network (CDN). Fastly provides the capability to automatically compress content, which can significantly improve load times and optimize the delivery of web resources. If you are interested in utilizing this feature, you can find comprehensive guidelines and instructions on how to enable automatic GZIP compression by visiting the following link: here.
