Downloading a file from the internet with '&' in URL using wget

Question

I'm trying to download a file from a URL that looks like this:

http://pdf.example.com/filehandle.ashx?p1=ABC&p2=DEF.pdf

Within the browser, this link prompts me to download a file called x.pdf irrespective of what DEF is (but 'x.pdf' is the right content).

However using wget, I get the following:

>wget.exe http://pdf.example.com/filehandle.ashx?p1=ABC&p2=DEF.pdf
SYSTEM_WGETRC = c:/progra~1/wget/etc/wgetrc
syswgetrc = C:\Program Files\GnuWin32/etc/wgetrc
--2011-01-06 07:52:05--  http://pdf.example.com/filehandle.ashx?p1=ABC

HTTP request sent, awaiting response... 500 Internal Server Error
2011-01-06 07:52:08 ERROR 500: Internal Server Error.

'p2' is not recognized as an internal or external command,
operable program or batch file.

This is on a Windows Vista system

Put the address in quotes, i.e.:

wget.exe "http://pdf.example.com/filehandle.ashx?p1=ABC&p2=DEF.pdf"
