Controlling cache

I have just read this interesting article again and still convinced an easy solution is not available to all.

http://stevenbenner.com/2010/12/caching-...rformance/

If the @IconFinder wants his searches to be cached, is having trouble with the $_GET parameters then he/she should investigate extracting the $_POST variable and building a URL.

Code:

// user search_string = 'this is a test to see if it works';
  // should clean results to eliminate ".,:l/\@", etc
  $tmp = str_replace(' ', '/', $_POST['users_search_string']);
  
  $url   = 'controller/method/' .$tmp;
  //$url = 'controller/method/this/is/a/test/to/see/if/it/works';

  redirect($url);
  
  // Controller function method() results shown with $this->uri->uri_string, or $this->uri->segment(1);

Why aren't you just using the uri functions and specifying site.com/search/q/cat or doing remapping and using simply site.com/search/dog

I would imagine these would cache just fine without some massive headache as my opinion is that the cache class was probably designed to ignore anything after an equal sign....

What are you talking about? In a week 90% of the searches have been done at least once before. There's a huge benefit of caching these results.

I would prefer to use HTML as intended with a form on the home page which uses GET and use URL parameters to the generate search results.

I'm talking about caching the whole page, because you would then get those results every time for any other keywords.

Even if only a part of the page is cached, it shouldn't search the database the second time a search term is used. I think there should be a way to use URI parameters as a part of the unique key for writing and retrieving cached pages. I don't understand why /search/dog is be supported but not /search/?q=dog

Unfortunately CI doesn't do that sort of thing out of the box. You'd have to either extend/hack around the cache library, or build your own caching system.

These forums seem to cache search results for a little while, maybe someone with access to the Expression Engine forums software could have a look at the code for it.
