I cannot log into stackoverflow sites using my myopenid account because where I work they do not allow long URLs and very long URLs are passed back and forth between stackoverflow and myopenid.
I looked at the URLs in Fiddler and I noticed a 302 redirect to https://www.myopenid.com with 17 query parameters. I login by passing the following six parameters through (of the 17):
and it allows me through.
I work for the public sector (government) where they are paranoid about security and they tell me that they cannot allow longer URLs because it is a security concern (I don't believe them).
This trick DOES NOT work with Google which is also uses a redirect. Is there a way of logging in using in to StackExchange without being allowed longer URLs? Login on Mobile and transfer cookies? A means of tunneling? Changing URLs seen in Fiddler/WireShark? etc.
