[Genome] Custom tracks

[Peter Chines]

Hello,

I notice that there have been big changes to the handling of custom
tracks.  While in general I think these changes are great, I'm having
some difficulty changing my programs to adapt to the new system, and
wonder if you can give me some pointers.

In the past, I used a local webserver to generate a redirect to the
URLs like the following:

http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg17&hgt.customText=http://fusion.nhgri.nih.gov/ucsc/nph-tracks.cgi?snp=rs5400%26pval=p_snp

This used to work, retrieving a set of custom tracks generated from our
local database and displaying them in the browser.

I have tried to adapt this to the new custom tracks system, but I've
found that even entering this URL:

http://fusion.nhgri.nih.gov/ucsc/nph-tracks.cgi?snp=rs5400&pval=p_snp

manually on the Add Custom Tracks page does not work (it simply returns
the Add Custom Tracks page again).  On the other hand, submitting the
actual text of the tracks does seem to work.  I am obviously doing
somethign wrong, but don't know what.  Any hints you could give would be
much appreciated.  Ultimately, I'd like to end up with a URL that I can
redirect my users to that will allow them to see our custom tracks
(which are generated on the fly, not stored) in the UCSC browser.

Thanks,
Peter
