Web updates with http

[SITL]

Hi Everybody,

How to specify user name & password in http URL ?
Earlier i have used ftp URL like this...
ftp://username:password@201.193.158.95/ ... Patch1.exe
it works fine.

Now we want to use http, I tried the same way of specifying the URL, use http instead of ftp
http://username:password@myWebsite/MyPr ... Patch1.exe

I'm getting the error as "Unable to contact update server"

Then i manually tried to access http://username:password@myWebsite/MyPr ... Patch1.exe
it's asking the login credentials.( It won't ask login credentials if i use ftp.)

So, Can anybody help me in specifying login credentials for http server ?
Appreciate your help.

Regards
