Page Caching extending it?

Hey there

Is it possible to intercept Action Cache to force it to use a
specified filename to save to… or to load a specified cached file
that is different to the current one expected for the URL?

I guess this is some sort of “extending” of action cache… but I
cannot find much in google :slight_smile:

thanks

Any clues anyone?

Interesting idea, but I’d ask the question, why would you want to do
this? Is there a real-world performance bottleneck your trying to fix
that wouldn’t be addressed with the standard page, action or fragment
caching ?

I need multiple cached versions of one page (/url) … tracked in
memcache… and I want to directly dump a page cache based on a
condition

Yes I know there are better ways to do this in rails… but I have
bad architecture to work with

So a light wrapper around Action Cache would be super awesome! … I
just can’t see anyone doing this

is it a version manager your want, something that lets you go back to a
previous page version?

Not a version manager

Its more about selecting content for different circumstances

Being able to cache different versions for a page/url and select it in
logic contained in a Action Cache wrapper seems the most appropriate

I’m just wondering if anyone knows of example of extending Action
Cache in a similar way, I’m not sure where to begin

I guess this could also be done by implementing some sort of Fragment
Cache… wrapping a whole page

Just not sure where to begin… I don’t want to reinvent rails
caching… just want to tweak it with a simple conditional + have
control on the file cache storage

Could you just do something like this:

<% cache(:action => “list”, :controller => “blah”, :style => “new”) do
%>

code that renders in either mode conditionally

<% end %>

You could also look at using something like cells, which has caching
built in and might be flexible enough to cache and render 2 different
views under the same action (depending on the circumstances).

+1 to fragment caching, as it is an easy-peasy solution to implement

Thanks for the replies guys.

I think I might be on the right track now

The documentation says: “Pressing shift-reload in the browser will cue
the browser and Varnish to regenerate the page, regardless of the
cache state.” http://devcenter.heroku.com/articles/http-caching

That goes against expectation… hope it’s an error :slight_smile:
