Hi I am a newbie and was wondering if some gracious soul could help out.
What I am trying to do, is post some data to a form, if the form sees
the key "secure_payload' in the query string it needs to perform an auto
login into the site vs a traditional login. It then redirects me to a
new page which I need to get the response and display
Rather when I try to follow the redirect url by doing a get
I get a
Method failed : HTTP/1.1 320 Found , when I do a post . Which is what
I expect as I need to follow this to the new resource.
<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="/AWD/login.aspx">here</a>.</h2>
</body></html>
Then it throws
java.lang.IllegalArgumentException: host parameter is null
I get no host ? I am confused? do I need to set some thing how does the
new url get know the host information ?
Appreciate your help
Thank you
Reeve
