Keeping Jot Placeholders Working on Cached Pages
A historical workaround for keeping Jot output alive even when the page itself remains cached.
Cached pages were great for speed, but they often collided with dynamic comment output. One of the classic problems was that Jot placeholders such as the form block or comments block would disappear or stop updating correctly when the page remained cacheable.
The practical workaround was to stop relying on raw placeholders alone and call the relevant Jot action more directly in a way that preserved the dynamic section while leaving the rest of the page cached.
Why this pattern mattered
- it let projects keep aggressive page caching without sacrificing comment functionality
- it reduced the temptation to turn off cache for entire sections just to keep Jot alive
- it reflects the old Evo habit of solving dynamic-output problems with targeted parser workarounds
Historical note
This kind of workaround is worth archiving because it captures the real trade-offs of the old Evo stack: speed often depended on cache, but interactive pieces still needed special treatment.
