Not necessarily. Assuming it starts with nothing in the cache, the
first request will cause CF to fetch the RSS feed and store it for two
minutes. Any subsequent requests in those two minutes will read from
the cache. After those two minutes, the next request will again cause
CF to fetch the RSS feed and store it for two more minutes.

No, it will not be sooner. CF has no way of knowing whether the RSS
feed changed without fetching it, which would defeat the point of
caching.

Using caching for a RSS feed

2014-09-26 Thread Chris h

Hi All, 

Below is the code which is being used for reading a RSS feed from a 
Wordpress(WP) site running Wordpress 3.9.1 
--
 
 
http://www.testsite.com/?feed=rss2";>;

 

 
  

   
#Left(tempTextNews, 75)#...more 
   
  
  #title#...more
  
 
 

 
  
  
   
 
 News Feed Temporarily Unavailable

For Application Server Caching, we have Cache Template in Request and Save 
Class Files enabled. Since lot of files are in ColdFusion, 
Trusted Cache is disabled.
 
 I added a basic cache so that the server running ColdFusion 9 reaches out to 
the server hosting Wordpress site every 2 minutes
 
 1. If 10(or 1000) people visit the webpage in an hour, where the above code 
exists, will it connect to the server hosting Wordpress site every 2 minutes 
for the RSS feed? 
 
 2. Or, will it be sooner if the RSS feed on WordPress changes between the 2 
minute interval?
 
Thanks
