Then just decorate your controller with [NoCache]. OR to get it done for all you could potentially just place the attribute within the class more info from the base class that you inherit your controllers from (if you have a person) like we have here:
seven Never set up this package deal to save four lines of code. Lowering dependencies must often be amongst your plans. Every dependency you add is another detail that needs to generally be updated, another method of getting your project hacked, another way to insert even more dependencies if this package adds dependencies, and so forth.

Sending the same header 2 times or in dozen parts. Some PHP snippets out there in fact replace prior headers, leading to only the last one becoming despatched.
It really is hacky, but no header-based Answer was working for me and for my purposes this little JS snippet is great (easy to transform to simple JS).
