Could someone give me some advice about caching please.
In a previous app I added a unique $_GET id to then end of every URL but I am sure there is a better way to achieve this in Yii. If the suggestions are header controls then could someone suggest where I put these within my app so they are applied throughout and if relevant which classes I might extend to do this.
Many thanks in advance.
PS. If anyone can suggest some good caching articles I would be grateful. I find it a bit of a black art
It’s not clear if you’ve already read Caching topic in docs, so if not, then it’s a good start point.
I am not talking about internal caching within the application using CCache component etc… I am talking about setting a concrete set of headers to prevent the client (browser) or any proxy server from caching my pages. I know that in theory most browsers do not cache pages requested through https, but it is the term ‘most’ that I am worried about. I am also not sure which headers proxy servers will always obey.
Take a look at this article: http://symfony.com/doc/current/book/http_cache.html
There is no "response" object in Yii, but still there is a good explanation of HTTP caching.
Many thanks. That is one of the best articles I have read. Just what I was looking for.
I assume that if I were to use PHP rather than apache e.g.
ini_set("session.cache_limiter","nocache"); This is best going at the start of index.php file?
