Hi Rob,
Changeset 7300:f197c4346cc4, which is currently available in galaxy-central, should allow the external display applications to work when require_login = True, thanks for reporting this error. Please let us know if you encounter additional issues.
Thanks for using Galaxy,
Dan

The problem seems to be in the lack of authentication by the request sent by IGV. The galaxy instance is set to require a username and password with "require_login = True" in universe_wsgi.ini, which means that when IGV attempts to download the BAM file at http://example.org/galaxy/display_application/e2132aef71b11dbf/igv_bam/local..., galaxy redirects to the login page.
I tried to remove the authentication requiements with the apache config (as per https://sites.google.com/site/princetonhtseq/tutorials/visualization-with-ga...):
<LocationMatch display_application/[a-zA-Z0-9]+/igv.*> RequestHeader set REMOTE_USER igv_display@example.org Satisfy Any Order deny,allow Allow from all </LocationMatch>But it didn't help. Commenting out the "require_login = True" line allows IGV to connect and download the bam file without issue.
I've now got IGV crashing when trying to access this BAM file, but that's probably a question for their list. -r

I'm trying to get IGV to download files served from the galaxy instance through "display_application". When IGV makes a request for the BAM file, it is re-routed to root like so:

Giving us a text/html page rather than the BAM file.
I see that I'm not the first person to run into this: http://lists.bx.psu.edu/pipermail/galaxy-dev/2011-December/007901.html but I'm still not really sure how to solve the problem.
I'm no sysadmin, so my apache config skills are very patchy. My config is up at https://gist.github.com/2970592. Any help would be very much appreciated.
