in NameValuePairs,
tos_agreed is a checkbox & I have assigned it 1. IAgreeBtn, has the same
value as the html source has - "Create My Account", action has the
formAction url. Other all parameters r proper, captcha is also entered
correctly. u, t r parsed from html source & taken dynamically & passed. I
had also added these parameters, but removed it as they remain same in all
pages.
//new NameValuePair("dracs", dracs), new NameValuePair("done", _done), new
NameValuePair("last", ""), new NameValuePair("partner", _partner), new
NameValuePair("src", new String()), new NameValuePair("intl", new
String("us")), new NameValuePair("jsenabled", new String("0")),
//, new NameValuePair("action", formAction)
// URL -> https://edit.yahoo.com/registration?.intl=us&new=1&.done=http
// formAction -> /registration;_ylt=A9FJpMTzzUJHpgIADgCZ2PAI
"POST /registration?.intl=us&new=1&.done=http&_ylt=A9FJpMBjCkRHERcBDgCZ2PAI
HTTP/1.0[\r][\n]"
This is the source of the post method & its required resources. Can anyone
know, where & what is the error? Why does the post refer to the same page
instead of next page. I am in very bad shape to solve this problem. Please
if, any one can help me out. Any help is highly appreciated.
Thanks
