I have problems with "gbrowse_img" URLs under my local installation using
centos 6.5
building perl v.5.18.1
installed latest cpan, bioperl and gbrowse using cpan:
as of 14/10/14: CPAN 2.05, BioPerl-1.6.923., GBrowse-2.55
If I clear the browsers cache (and apparently the gbrowse cookie which stores the session id called "gbrowse_sess") and directly go to a ../gbrowse_img/.. "add" URL
(e.g.:
) I see that there it creates the missing "gbrowse_sess" cookie.
If I than go to a ../gbrowse_img/.. URL with ADD parameter it works because the cookie has been set before.
So the problem is that there is code in the gbrowse which creates a session id cookie only when browsing to the standard gbrowse pages and not in gbrowse_img with "add" parameter.
Since our website makes requests to our gbrowse server through ../gbrowse_img/.. URLS only using the ADD parameter
my suggested solution would be to create the missing session id and cookie on the ../gbrowse_img/.. requests if it is not available (e.g. from clearing browser), etc.
Try on your own (tested in Firefox 33):
clear browser cache OR "gbrowse_sess" cookie, than:

So I need to create the whole bunch of session initalization such as creating a session directory.

now it works!
Can someone confirm this is a bug or fix this?
I tried calling
