Giving Access Denied error ini IE7/8 and NS_ERROR_PROXY_CONNECTION_REFUSED in firefox
<p>I am using JQuery, FLXHR for Cross browser authentications.</p>

<p>I have implemented JQuery FLXHR to my project, all is working fine till I am using the same domain for example if my login page is (http://staging/login/loginpopup.aspx) and its sending the request to (http://staging/login/login.aspx) for user authentication it works great, just when I change it for HTTPS request, I mean when I send to HTTPS request (https://staging/login/login.aspx) from HTTP it is giving error "text/html (NS_ERROR_PROXY_CONNECTION_REFUSED)" in firefox and "Access Denied" error in IE7 and IE8.</p>

<p>If I see in <strong>Response Header</strong> in HTTPFOX it shows below content.</p>

<pre><code>(Status-Line)   HTTP/1.1 407 Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied.  )
Via 1.1 DXBMIPX12
Proxy-Authenticate  Negotiate
Kerberos
NTLM
Connection  close
Proxy-Connection    close
Pragma  no-cache
Cache-Control   no-cache
Content-Type    text/html

</code></pre>

<p>Please suggest what I am missing or what changes are required to fix it.</p>
