@NotWegant (Sorry for my English).
When you make a GET request in the response, you will have cookies for this URL. Then you will save them. Is this option not working?
@Omini yes, I just tried this way too, it still seems to cut-off at 1,000,000 bytes, so it wasn't related to breaking due to content etc, it still seems to be a data length / quota memory problem
@kmishu96 The first thing is u need to record the http request from hotmail signup page till finish, and use the http record/sniff result, its not easy bcoz microsoft/hotmail have much protection etc. or u sniff all request from another sniff program and put into BAS :)
