You need to base64 encode your username:password and then prefix it with Basic. It will end up looking something like:

Authorization: Basic VEFWSVNcZGFycmVsOg==

You then enter this in the request headers field.

Darrel, what format should the text file that I am encoding be in? It looks like when it gets decoded on the server I am getting ????username@domain.com. I am guessing these are spaces but I don't have any leading spaces in my file. – Peter Feb 10 '11 at 14:46
@Code Sherpa What textfile? In the RequestBuilder tab in fiddler, there is a Request Headers textbox. Just paste your authorization header in there. – Darrel Miller Feb 10 '11 at 15:04
Yes, but the username:password needs to be encoded into a base64 string first... I have a utility that takes a file and outputs the contents to base 64 but am getting leading ????. – Peter Feb 10 '11 at 15:11

OK, the Fiddler Text Encode/Decode utility worked... I forgot about this. Thanks for your help – Peter Feb 10 '11 at 15:17

@Code Sherpa I had no idea about that Fiddler utility :-) Now I do! – Darrel Miller Feb 10 '11 at 15:28

For the record, this handy utility (which I also just discovered) is in `Tools -> Text Encode/Decode...`. – ladenedge Jul 12 '11 at 01:51

In Fiddler 4.4.2.1 (beta) it's in `Tools -> Text Wizard`. :) – Leniel Maccaferri Nov 27 '12 at 01:58
