Hi Nate,
I have checked the nginx.conf file and they comply to the documentation:
# added to allow nginx to handle file downloads location /_x_accel_redirect/ { internal; alias /;
I have also confirmed that the universe_wsgi.ini file contains the following:
And the following to the [app:main] section of universe_wsgi.ini: nginx_x_accel_redirect_base = /_x_accel_redirect

This will need some in-depth debugging, then. If you access Galaxy directly via the port of its built-in web server (by default, 8080), and request to display a dataset, does it set the X-Accel-Redirect header in the response? If you access the same dataset via the nginx address but rename the underlying disk file, do you get an error message from nginx or from Galaxy? --nate

Hi Everyone,
I have been tasked with getting the IGV working within our Galaxy instance. I have modified our Nginx configuration based on the more advanced configuration under "Sending files using nginx" on the nginxProxy page in the wiki. The IGV viewer component in Galaxy does not display the results from a BAM file in either the web or local instance of IGV. I have tested with IGV1.5 and with version 2.03. Neither produce a visual representation of the sequence. When attempting to use the web option we get the same error provided in the original post as noted below. Has anyone gotten this to work with Nginx-0.8.53 or any of the newer versions?
Hi Iry,
Have you checked to make sure that your nginx server is serving the file for download, as opposed to the internal Galaxy web server? In the original email, it looked like nginx was being bypassed entirely (due to serving on port 8080 - Galaxy's intenal server's default port). But even once nginx is in use, it's necessary to set up X-Accel-Redirect to serve datasets. See the instructions here:

On Apr 27, 2011; 10:06am ³Hello all, I just updated our local copy of Galaxy and just wanted to try the new IGV display application. When I try to display a BAM file with the local IGV or the web IGV I encounter following error complaining about the Null content-length. Has any of you encountered the same problem? Do I miss something? Thanks in advance

On Apr 27, 2011; 12:33pm ³Hi Alex,
Displaying BAM files at external applications usually requires an http server that supports partial gets. Unfortunately, the current lightweight http server that is built into Galaxy does not support these advanced http options. However, this limitation can be overcome by using a proxy server that is able to handle http1.1 requests. Please see "Using a Proxy server" at https://bitbucket.org/galaxy/galaxy-central/wiki/Config/ProductionServer for help on setting this up.
Thanks for using Galaxy,
Dan²
On Apr 27, 2011; 9:07pm ³I¹m getting this same error and I¹m running nginx as a proxy server. Is there a specfic parameter we should be aware of to allow partial gets? I don¹t see anything in the wiki page for setting up the ProductionServer.
Thanks,

On May 04, 2011; 7:47am ³Could someone who has successfully gotten the IGV tool to work using NGINX as your proxy, tell me if there was anything specific they needed to do with their NGINX or galaxy config to get it working?
