Problems with URL Syntax

[Jerry Spence1]

I am trying to get a jpg image as follows:

Dim Client As System.Net.WebC lient = New System.Net.WebC lient
Client.Download File("http://root:<password> @192.168.0.99/cgi-bin/video.jpg",
MyFilename)

However I understand that IE no longer supports this 'in-line' presentation
of the username and password strings. Indeed I am getting a "Not Authorized"
error being returned.

Although I'm not using IE directly, are the components (and the security
contraints) of IE still being used in the background?

Has anyone met this before and is there a work around?

Thanks

-Jerry

It's nowhere specified that username and password can be embedded inside
HTTP URIs (this does not apply to FTP URIs though), and only some browsers
supported this sort of URIs. However, embedding username and password into
URIs is a very bad idea for security reasons. Instead you may want to check
out the 'WebClient' object's 'Credentials' property which can be used to
pass authentication data to the server.

No, 'WebClient' has nothing to do with IE. It was simply IE which provided
functionality which was not standard compliant and insecure and has been
abandoned for this reason.

Credentials worked a treat. Thank you so much!
