you mentioned that you use realurl. Realurl can cause tslib_fe to disable
caching due to cHash mismatches.
How to check:
- disable realurl and look to the admin panels no_cache output. If it still
says no_cache: 1 than another extension seems to be the culprit.
- enable the first 4 checkboxes in section "TypoScript" in the admin panel
(escpecially "Display messages:"). Now you should see if caching was
disabled by a cHash error.
