Question : Switch between HTTP and HTTPS pages using vb.net

I have installed SSL on IIS 7. I have a master page with a menu that contains login item and home item.
When login is clicked you are redirected to a login page when home is clicked you are redirected to the home page. All works fine untill I installed SSL. When I click Login from the menu I get an error saying that the page must be viewed over a secure channel. My code has a response.redirect(https://login.aspx)

Answer : Switch between HTTP and HTTPS pages using vb.net

Need more information. If the switchport is not configured with a voice vlan (Cisco environment) then both the phone and PC would send DHCP broadcasts in the default vlan. The PC could pull an IP address and access the network as usual. But the IP phone could be missing info it needs from the DHCP server like option 150 which tells the phone the IP address of the TFTP server.....the PBX could be also be offline.... Lots of possible scenarios here.
