Is there any way to access to a public content directly via a link?. I will explain myself... I know that I can share the public content link, for instance https://campus.elearningsolutions.es/webapps/blackboard/execute/content/blankPage?cmd=view&content_id=_2293_1&course_id=… , but the first time you access to this link you will get the "receiptNotAvailable" page. If you access the link for a second time you will get the content without problems. I think that is because the session_id and/or the s_session_id cookies are not set in the first request.
I don't know if it is possible to get the cookie and attach the session ids to the request using rewrite_mod in an Apache2 server. I am using one to create redirections to use friendly urls to the contents.
