Need help with nginx directives for MODX Cloud

Hi,

I have 2 problems with rewrites for MODX Cloud:

1. Rewrite static.mydomain.com to assets folder

I want this subdomain to point to the /assets/ folder of my Cloud. I tried to set the root for this subdomain like this:

location / {
	
	if ($host = 'static.chsmedien.com') {
		root /paas/cxxxx/www/assets/;
	}
	
	try_files $uri $uri/ @modx-rewrite;
}

...but this is not working.

2. Send retina images based on cookie

Based on this http://shauninman.com/tmp/retina/, I'm setting a cookie in the browser and the webserver should send @2x images. But this doesn't work, too.

location ~* \.(?:ico|gif|jpe?g|png)$ {
    expires 355d;
    
    # Serves static files in high resolution only if required
	# Naming convention for high resolution images:
	# [filename]@2x[extension], e.g.:
	# [email protected]
	set $hidpi_uri $1@2x$2;
	
	if ($http_cookie !~ 'device-pixel-ratio=2') {
    	# If the device-pixel-ratio cookie is not set to 2, fall back to
    	# default behaviour, i.e. don't try to serve high resolution image
    	break;
    }
	
	# device-pixel-ratio cookie is set to 2
	# Serve high resolution image if available,
	# otherwise fall back to standard resolution
	try_files $hidpi_uri $uri =404;

}

My complete rules:

# x-ua-xompatible header
add_header X-UA-Compatible IE=edge,chrome=1;



# expire headers for assets
# 1: images
location ~* \.(?:ico|gif|jpe?g|png)$ {
    expires 355d;
    
    # Serves static files in high resolution only if required
	# Naming convention for high resolution images:
	# [filename]@2x[extension], e.g.:
	# [email protected]
	set $hidpi_uri $1@2x$2;
	
	if ($http_cookie !~ 'device-pixel-ratio=2') {
    	# If the device-pixel-ratio cookie is not set to 2, fall back to
    	# default behaviour, i.e. don't try to serve high resolution image
    	break;
    }
	
	# device-pixel-ratio cookie is set to 2
	# Serve high resolution image if available,
	# otherwise fall back to standard resolution
	try_files $hidpi_uri $uri =404;

}
# 2: js/css
location ~* \.(?:js|css)$ {
	expires 30d;
}



# Built-in filename-based cache busting
# This will route all requests for /css/style.20120716.css to /css/style.css
# Read also this: https://github.com/h5bp/html5-boilerplate/blob/master/doc/htaccess.md#cache-busting
location ~* (.+)\.(\d+)\.(js|css)$ {
	try_files $uri $1.$3;
}






# modx furls rewrite
location / {
	
	if ($host = 'static.chsmedien.com') {
		root /paas/c0073/www/assets/;
		break;
	}
	
	try_files $uri $uri/ @modx-rewrite;
}

@christianseel - i'd love to know how to get these working too. Have you tried contacting cloud support? They're very responsive.

out of interest - have you tried adding "static.chsmedien.com" to your domains under that particular cloud?

Yep domain is added. Didn't ask support...

Hi Christian,

I think I can help with the first problem.

Your test to see if the $host is "static.chsmedien.com" is in the location / {} block. However, any requests for assets are probably matching your (?:ico|gif|jpe?g|png) or js|css location blocks. Only one location block is used for a request, unless the request is rewritten.

I would suggest moving this conditional out of a location block altogether (i.e. to near the top of the rules), and doing a rewrite instead:

if ($host = 'static.chsmedien.com') {
  rewrite ^ /assets$uri last;
}

Hope this helps.

Wouldn't hurt to add the following in your rules too:

if ($host = "www.chsmedien.com") {
  rewrite ^ $scheme://chsmedien.com$uri permanent;
}

Thanks netProphEt, that helped! I did not know that only one location block is used, that makes it quiet more complicated.
Your suggestion works, as far as I can see. But the retina rewrite still doesn't work.

My complete rules now:

# x-ua-xompatible header
add_header X-UA-Compatible IE=edge,chrome=1;


if ($host = 'static.chsmedien.com') {
  rewrite ^ /assets$uri last;
}


# expire headers for assets
# 1: images
location ~ ^(/images/[^\.]+)(\.(?:jpe?g|png|gif))$ {
    expires 355d;
    
    # Serves static files in high resolution only if required
	# Naming convention for high resolution images:
	# [filename]@2x[extension], e.g.:
	# [email protected]
	set $hidpi_uri $1@2x$2;

# disable this for testing...	
#	if ($http_cookie !~ 'device-pixel-ratio=2') {
    	# If the device-pixel-ratio cookie is not set to 2, fall back to
    	# default behaviour, i.e. don't try to serve high resolution image
#    	break;
#    }
	
	# device-pixel-ratio cookie is set to 2
	# Serve high resolution image if available,
	# otherwise fall back to standard resolution
	try_files hidpi_uri $uri =404;

}
# 2: js/css
location ~* \.(?:js|css)$ {
	expires 30d;
}

location ~* (.+)\.(\d+)\.(js|css)$ {
	try_files $uri $1.$3;
}



# rewrite blog/rss to feedburner

	try_files $uri $uri/ @modx-rewrite;
}

Okay, I got also the 2nd working. The problem was the location block, the rewritten assets folder was missing.

# x-ua-xompatible header
add_header X-UA-Compatible IE=edge,chrome=1;



if ($host = "static.chsmedien.com") {
  rewrite ^ /assets$uri;
}



location ~ ^(/assets/images/[^\.]+)(\.(?:jpe?g|png|gif))$ {
    expires 365d;
    
    # Serves static files in high resolution only if required
	# Naming convention for high resolution images:
	# [filename]@2x[extension], e.g.:
	# [email protected]
	set $hidpi_uri $1@2x$2;

	if ($http_cookie !~ 'device-pixel-ratio=2') {
    	# If the device-pixel-ratio cookie is not set to 2, fall back to
    	# default behaviour, i.e. don't try to serve high resolution image
    	break;
    }
	
	# device-pixel-ratio cookie is set to 2
	# Serve high resolution image if available,
	# otherwise fall back to standard resolution
	try_files $hidpi_uri $uri =404;

}



location ~* \.(?:js|css)$ {
	expires 30d;
}



# rewrite blog/rss to feedburner
rewrite  ^/blog/rss$  http://feeds.feedburner.com/chsmedien  permanent;



# modx furls rewrite
location / {
	try_files $uri $uri/ @modx-rewrite;
}

The only thing that is missing is filename-based chaching rewrites:

# Built-in filename-based cache busting
# This will route all requests for /css/style.20120716.css to /css/style.css
# Read also this: https://github.com/h5bp/html5-boilerplate/blob/master/doc/htaccess.md#cache-busting
location ~* (.+)\.(\d+)\.(js|css)$ {
	try_files $uri $1.$3;
}

This would be again in confilct with the existing location block for css/js files. But I currently have no idea how to combine them.
