Cache handling

[tanczosm]

Is there any attention to how browser caching is handled with requests that return full or partial results on the same url?

See https://htmx.org/docs/#caching

I want to support this through the standard aspnet core Output caching functionality, and as far as I can tell, it should just work (at least it does in regular Blazor SSR).

Will need to experiment and make sure htmxor has not broken anything related to it though. Another source of inspiration may be: https://github.com/dotnet/aspnetcore/issues/49130

This is related to #18.

I confirmed that it "just works" with [OutputCache] and friends and Htmxor. However, current Htmxor is setting a xsrf cookie token on each request, which prevents caching from working, as caching disables itself when a cookie is set. So I will revisit the antiforgery token stuff.

I would recommend OutputCache only be applied on non-mutating HTTP methods like GET which also don't require anti-forgery tokens. For mutating endpoints/functions (POST, PUT, and DELETE), folks should rely on server-side caching.

Good point Khalid. Then it should just work now.

[tanczosm]

To be clear, if I know I'm going to be rendering potentially different content from the same endpoint url (full page vs partial page) depending on whether it's an htmx request or not I'm going to need to decorate each page with something like:

@attribute [OutputCache(VaryByHeaderNames = ["HX-Request"])]

I think so @tanczos.
