  1. Go to the My Collections at HathiTrust.org. Note that this interface is different from the Workset builder that will be on the HTRC's [http://analytics.hathitrust.org] site.

  2. Click the yellow "Login" button on the My Collections page. This will redirect to CAS, which will then redirect to shibboleth (at least on IU's network): [https://cas.iu.edu/cas/login?cassvc=IU&casurl=https://idp.iu.edu/shibboleth-idp/Authn/RemoteUser?] On other networks, they may go to another login protocol, but the important thing is that they will go through to return a Shibboleth token back to HT.

  3. Shibboleth returns to hathitrust, which then does a POST request containing the body of the SAML response to [https://babel.hathitrust.org/Shibboleth.sso/SAML2/POST]

  4. The POST Response from [https://babel.hathitrust.org/Shibboleth.sso/SAML2/POST] tells us to set some cookies:

  5. Final request to collections page uses a Cookie containing the shibboleth session: [https://babel.hathitrust.org/shcgi/mb?colltype=my-collections]

  6. When requesting a particular collection (e.g., [https://babel.hathitrust.org/shcgi/mb?a=listis;c=1181879677]), the cookies are also set with the session token.
