Content / StatusCode is not allowed

In the past weeks I often used the function:

Import[~~~, "XMLObject"]

which works fine, except from the following frequent error:

URLFetch::noelem: The element “StatusCode” is not allowed. >>

along with the suggestion to configure the firewall.


I realized that I can achieve the same thing, a bit faster, with

URLFetch[~~~]

But, now I get a slightly different error:

URLFetch::noelem: The element “Content” is not allowed. >>

Can anyone tell me if this can be avoided? (I would need to collect some real-time data)
