post-check=0, pre-check=0',

post-check and pre-check were introduced by Microsoft for IE 5–8 (around 2000–2009).
They allowed IE to serve cached content while asynchronously checking for updates (pre-check) or revalidating after serving (post-check).
Other browsers never supported them—Chrome, Firefox, Safari, and Opera ignore them completely.

unless we need to support ie <8 then these are useless

Thanks for info. I did not checked other parameters.
We can remove these also.
