The session is from your mysqli code when it is run on my page. If I have a a dynamic page where a URL variable is changing the content of the page it is beneficial from a resource stand point to cache that content. So if test.php?id=1 is different from test.php?id=2 why not cahce on my CDN? Which is what I am trying to do, but it appears the MYSQLi server behavior is overriding my server headers. Since I did not write the code for this extension, basically I am asking how do I edit it to stop it from breaking my headers and preserve the integrity of the code I purchased?
