If you fill the session cookie with 4kb of data, that means every http request after that to that domain will require the user to upload 4kb of data, which may not seem like much, but on a mobile phone for instance, loading a page with 50 images, that becomes 4*50 = 200kb - pretty significant considering most home internet connections do not have very fast upload in many countries. On my own internet on a good day that’s at least 2 seconds of uploading.
So it is best to use session cookies only to store a very small identifier, then store more information in a local database or file. If you have a look in the rack project you’ll see some other session handlers which do exactly this, so you can keep writing data in to the ‘session’ but have it stored locally, with only a small cookie with an ID number to lookup the local data stored in to the browser. — Bluebie On Saturday, 7 December 2013 at 8:27 am, Charles McKnight wrote: > Sure wish the W3C would devise a better state mechanism than cookies... > > On Dec 6, 2013, at 12:49 PM, Magnus Holm <judo...@gmail.com > (mailto:judo...@gmail.com)> wrote: > > > You should not store a large amount of data in the session.
