[gradebook2-dev] FW: Gradebook Issue

Fri Oct 8 23:16:00 PDT 2010

I know why.

We use SakaiPortalLogin.jws for SSO logins, and stupidly all our
sessions are logged saying that SakaiPortalLogin.jws is the user agent,
not the actual browser (it's the agent used to create the original
session)

I had opened a bug on this asking to see if the user agent is
SakaiPortalLogin.jws, to update it when a person actual get's in with
their real browser, but they said they won't fix.  Up until now it's
just been an annoyance to lose that information for logging purposes,
but now it's actually causing problems.

But then again, now that I'm thinking about it, when testing in
development I'm not doing SSO to log in, I'm logging in straight, so the
user agent should be set correctly.

Hmmm....  Like I've said earlier, we were already having problems with
IE8 also.  I'm thinking just looking at the user agent isn't the right
answer.

Jeremy,

We just added a patch to:

http://jira.sakaiproject.org/browse/GRBK-665

... it changes the minimum version from 8 to 7 for removing the cache
directives. Could you please test this in our DEV environment? Also,
could you please send us the request information in a case where you see
this error occurring for  IE 8. We tried several systems that have IE 8
and we cannot reproduce this problem. Meaning our code in:

https://source.sakaiproject.org/contrib//gradebook2/trunk/server/src/jav
a/org/sakaiproject/gradebook/gwt/sakai/rest/resource/Export.java
<https://source.sakaiproject.org/contrib/gradebook2/trunk/server/src/jav
a/org/sakaiproject/gradebook/gwt/sakai/rest/resource/Export.java> 

removes the cache directives. Any help/information that you can provide
is greatly appreciated.

Best,

-- Thomas

Yup, sure enough I commented out the two no-cache headers from
server/src/java/org/sakaiproject/gradebook/gwt/server/RestServlet.java
and it's working in our development environment.

Will do.

It looks like it's an https issue.

We are fronting tomcat with Apache in our development environment,
apache is doing the SSL termination.  In our production environment our
load balancer is doing the SSL termination (but still going through
Apache too (don't ask))

This is true. Jon commented in GRBK-665: "for ie8 over https, we had to
remove the Pragma and No-Cache headers from the response "

We are running in the same environment where we front tomcat with
apache.

	Anyway, in development, the export works fine when I talk
directly to tomcat, or through non SSL apache.  But as soon as I hit the
site with SSL we get the error.

	This is feedback I'm getting from faculty on this issue, I'll
test out the works okay for an instructor but not logged in as
themselves and get back to you.

	A few responded on the IE version, they are using IE7.

	Jeremy,

	I think this is related to
http://jira.sakaiproject.org/browse/GRBK-665. What version of IE are you
using. From your problem description, it seems that there may be a new
wrinkle to this issue. You said that if you use the same version of IE,
it works for an instructor but not if you are logged in as yourself, is
that correct?

	We may have to reopen GRBK-665 or just create a new JIRA.

	Best,

	-- Thomas

	Hey Guys,

	Just a heads up on an issue that I ran into with Sakai this
morning and it seems to be restricted to IE.  If you add yourself as a
participant to a course then enter it as yourself and try to export to
CSV from gradebook, it gives you the error shown in my screenshot.  This
doesn't happen if you login as the instructor and this doesn't happen at
all in Firefox.  Not sure what can be done about it but just thought I'd
point it out.
