Dear all,

please can you help me to fix the issue with try_files an regex 
location, thank you.

I use

###
sbin/nginx -V
nginx: nginx version: nginx/1.1.4
nginx: built by gcc 4.4.3 (Ubuntu 4.4.3-4ubuntu5)
nginx: TLS SNI support enabled
nginx: configure arguments: --with-debug --with-libatomic 
--without-http_ssi_module --without-http_uwsgi_module 
--without-http_scgi_module --without-http_memcached_module 
--with-http_ssl_module --user=nginx --group=nginx --prefix=server/nginx 
--with-http_stub_status_module
###

with the following config.

###
http {
   server {
...
         location ~ ^/(share|alfresco)(/res)?(.*$)  {
           alias /home/alfresco/alfresco-4.0.b/tomcat/webapps;
           try_files $uri /$1$2 /$1$3 @alfresco;
         }

         location @alfresco {
           proxy_pass   http://alfresco;
         }
   }
}
###

I get the following error:

###
2011/11/11 12:58:09 [error] 5618#0: *33782 open()
"/home/alfresco/alfresco-4.0.b/tomcat/webapps/share/components/document-details/document-link/home/al" 
failed (2: No such file or directory), client: xxx, server: xxx,
request: "GET /share/components/document-details/document-links-min.js 
HTTP/1.1", host: "xxx", referrer: 
"https://xxx/share/page/site/aleks-glossar/document-details?nodeRef=workspace://SpacesStore/985297e8-ff1b-4423-b6e9-8dacc0011196"
###

Could it be that try_files match on '/$1$2' but the open call get 
'/$1$3' or something else?

attached the debug log.
