bug#21524: 24.4; eww POST variable sending error

[vidyuth]

I am running a picolisp application server locally. It works fine in
Chromium and w3m (in emacs) browsers respectively.

I type M-x eww
Enter URL or Keywords: localhost:8080

the page loads fine.

in the login section on the page I enter both user name and password

I see an error in the server session which is not normal, I am denied
access.

the server gets the username and password via POST. something is wrong
in eww while sending the POST variables. not sure how to check the post
variables either.
