Hi, this simple patch modifies xslt_filter module to make it possible use location (and not server cwd) relative paths in xslt_stylesheet directive. It should simplify a bit stylesheets deploying.

It's mostly a reorganization patch, stylesheet parsing has been moved to merge handler + fully relative stylesheet paths are being prepended with current location root. I can improve it if there some problems...

I test this with nginx version 1.4.4 and 1.6.0

When setting up nginx as a load balancer, i notice some weird behavior

Step to reproduce

1. enable default site '000-default'. create another site to be tested. (i did not see this behavior if there is only one site)

2. create post

GET /users/current.json HTTP/1.1 Host: lb.somehost.com X-SESSION_FOO: 9abcdef999999abcde.99999999

nginx will forward X-SESSION_FOO

3. another post with custom session above host

GET /users/current.json HTTP/1.1 X-SESSION_FOO: 9abcdef999999abcde.99999999 Host: lb.somehost.com

nginx will NOT forward X-SESSION_FOO

4. another post without underscore

GET /users/current.json HTTP/1.1 X-SESSION-FOO: 9abcdef999999abcde.99999999 Host: lb.somehost.com

nginx will forward X-SESSION-FOO

Some information

# /etc/nginx/sites-enabled/api.local upstream api_general {

server 10.0.0.1

; }

server {

listen *:80; server_name lb lb.somehost.com

access_log /var/log/nginx/api.local.access.log timed_combined; error_log /var/log/nginx/api.local.error.log;

underscores_in_headers on; add_header Access-Control-Expose-Headers "X-SESSION_ID, Content-Type, Location";

location / {

proxy_pass ​http://api_general;

}

}

If we put nginx proxy_cache_path and proxy_temp_path nginx configuration directives to the same xfs partition, cache manager calculates the size of cache improperly (it adds some 20-30%). It shows proper size only after the nginx restart. If we put proxy_temp_path to different partition, the size is properly calculated all the time. But that brings us unnecessary I/O load for moving files between partitions. We didn’t have this issue with ext3 partition.

Below are examples that show how cache manager sees the cache size during the 2 GB file download/caching. As we use ‘slice’ nginx directive, it shows 10 files, each one of them 200Mb size big.
