Added a new HTML comment, "Cached page generated by Solid Performance on $date" to indicate caching is active when debug mode is disabled.
Introduced the X-Cached-By: Solid Performance header to clearly identify cached responses in browser dev tools.
Implemented intelligent cache purging that clears related pages when a post is changed, including home pages, taxonomy, author, and date archives, and their paginated counterparts.
Improved overall code structure and performance for better efficiency and maintainability.
Fixes
Fixed an issue where using the "Exclude from Page Cache" meta option would not immediately purge the post from the cache.
