serve assets from a different hostname
2 August 2009 at 11:41pm Last edited: 2 August 2009 11:42pm
Hi,
in order to maximize parallel download:
http://www.websiteoptimization.com/speed/tweak/parallel/
I would like to serve all the files stored in the /assets/ folder from a different hostname, like static.mywebsite.com (that points to the same host)
In few words I would like that all the articles containing links to the /assets/ folder, be rewritten from:
mywebsite.com/assets/image.jpg
to:
static.mywebsite.com/image.jpgdo you have any hint?
thanks,
kochab -

AFAIK links to assets aren't created using shortcodes, so no luck with that..
But you could still write a custom TextParser that replaces all links in your content.
The page about TextParser apparently no longer on doc.silverstripe.org, but just look at the implementations in sapphire/parsers -

I had to hack Image::getTag as well to replace urls in ImageObjects to be able to use $Object.Image etc:
function getTag() {
if(file_exists("../" . $this->Filename)) {
$url = $this->URL();
$title = ($this->Title) ? $this->Title : $this->Filename;
$url = str_replace('/assets/','http://assets.mydomain.com/assets/',$url);
return "<img src=\"$url\" alt=\"$title\" />";
}
}
I also use a isDev switch in Page_Controller init() to use the static domain only in live mode for css and js :public function init() {
parent::init();
if(Director::isDev()){
Requirements::css("themes/".SSViewer::current_theme()."/css/blah.css");
Requirements::Javascript("mysite/javascript/blah.js");
} else {
Requirements::css("http://assets.mydomain.com/themes/blah.css");
Requirements::Javascript("http://assets.mydomain.com/mysite/javascript/blah.js");
}
}Never tried the TextParser. If you try it, pleas post results

Second solution is the best i'll just add some getter and setter functions and it'll be easy to configure assets image domain.
Thx! =)
Image is just extending File
So we can modify getURL function and add Director::assetsURL() methodsapphire/filesystem/File.php:
..
function getURL() {
if(Director::assetsURL()){
return Director::assetsURL() . $this->getFilename();
}else{
return Director::baseURL() . $this->getFilename();
}
}
..So all static files will be on the other domain, not only images
