Is there a way to tell curl to not use cache

Question

I am trying to find out file size of an url:

$url1 = \'www.google.com\';
$curl1 = curl_init();
curl_setopt($curl1, CURLOPT_URL, $url1); 
curl_setopt($curl1, CURL         


        

Answer 1

The best way to avoid caching is applying the time or any other random element to the url, like this:
$url .= '?ts=' . time();

so for example instead of having
http://example.com/content.php
you would have
http://example.com/content.php?ts=1212434353
