[Radiant] Increasing Page Cache Timeout

[Mohit Sindhwani]

Hi, just a quick question - how do I increase the page caching from 5
minutes to something much more?

My site has mostly static content other than the use of the comments
extension which itself clears the cache when the page changes. I think
it would make a great difference to the performance to set the cache
time out to a much larger value.

My understanding is that I should add a line to
MYRADIANTAPP/config/environment.rb where it says:
# Response Caching Defaults
ResponseCache.defaults[:directory] =
ActionController::Base.page_cache_directory
ResponseCache.defaults[:logger] = ActionController::Base.logger

Would that be correct?

Thanks,
Mohit.

i can't recall exactly how it worked in 0.7 (search the radiant source
for "5.minutes" and you'll find the code that controls it) but in 0.8
there is a method on SiteController called cache_timeout that you use
to set the timeout to whatever you like. i stuck
`SiteController.cache_timeout = 60.minutes` in environment.rb fired up
a rails console, ran SiteController.cache_timeout.value and sure
enough i get 3600 back.

in something less than 0.8.0:

ResponseCache.defaults[:expire_time] = 12.hours

Otherwise, in 0.8.0 and greater, john is right:

SiteController.cache_timeout = 12.hours

Thanks John and Jim,

I did what you suggested and came up with this in
\vendor\radiant\app\models\response_cache.rb
@@defaults = {
:directory => ActionController::Base.page_cache_directory,
:expire_time => 5.minutes,
:default_extension => '.yml',
:perform_caching => true,
:logger => ActionController::Base.logger,
:use_x_sendfile => false,
:use_x_accel_redirect => false
}

So, I guess, as Jim clarified, I would need to add:
ResponseCache.defaults[:expire_time] = 12.hours

That should do it! Is anyone using really large numbers like 2400.hours?

Thanks,
Mohit.
