[SOLVED] ERR_CACHE_MISS error when click back button

[Krlos]

Hi, I have a page with a form for searching field data. After the results are shown I have a link to view details for every result match.

Everything is working fine but after I click to view a detail and try to go back to the results page I get ERR_CACHE_MISS on Chrome  and Firefox.

I have been reading about this issue here

The solutions posted is to add this headers to the page:

header('Cache-Control: no cache');

How can I add this header to a template?

Thank you

You should not use "post" but "get" for a searchform. This way it's not trying to resubmit the form. 

The design pattern when using "post" for Forms usually is PRG https://en.wikipedia.org/wiki/Post/Redirect/Get

Thank you @Soma, you were absolutely right.

Using get instead of post fixed my problem!
