This is a critical bug fix release that relates to session handing in Internet Explorer.
Added "Expires" to cookie expiration time handling that is supported by IE.
Prior to this release, cppcms session cookies used max-age option, that IE does not recognize. Starting from this release the session cookies would have both Expires and Max-Age options. All browsers that use Max-Age would ignore Expires if both given.
New options that control the session cookie properties are added, see expiration_method that would allow to alter the behavior and handle possible clock skew issues
Special thanks to Saikumar Gandapodi who reported me this issue.
