Help with MS Internet Transfer Control

[Alexey Titov]

Hi :)

Got this strange problem with MS Internet Transfer Control (SP6)

I have two PCs with different IPs
Trying to access a particular website
First PC's IP is blocked on that site and I get 'You're not authorised ...'
response
Second PC's IP is not blocked and I can access the site fine
When (on the first PC) in InternetExplorer I set a proxy - I can access that
site from the first PC.

Then I have some VB code - it uses the MS Internet Transfer Control to read
data from the site

Set HTTPControl = New Inet
HTTPControl.Proxy = "http://123.123.123.123:8080"

this code works fine on the second PC, which is not blocked on the website,
and it indeed uses proxy to access the site
But on the first PC - it returns same 'You're not authorized ... ' response
(code 403.6) :(

Can anyone tell me why, while it is indeed using proxy, it still gets
blocked?

Regards,
Alexey
