I am working on writing a coldfusion based RETS system. I pretty much have everything figured out except for the authentication portion.

I am connecting to the rets server twice to facilitate authentication. The first time I connect I get a wanted 401 error. I use this error to create my full authentication string. This works as intended.

The issue I am having is when I use the created Authentication string to create my header which I post to RETS server. I know what the problem is, it is how I am formatting my header. I still have yet to find a black and white example of how this header should be created. Below are the headers that I am creating and passing. I have replaced private info with **'s

Any help with this is greatly appreciated.


Created Header:
Authorizationigest qop="auth", User-Agent="MRIS-test2/1.0",username="****",password="*****",nonce="5aeab 8af7e8e241f07ea0c3868584f12", opaque="17051842362549", uri="/rets/login" 400 Incorrect prefix YES

Passed Header + Error:
HTTP Status 400 - Incorrect prefix <Authorizationigest qop="auth", User-Agent="MRIS-test2/1.0",username="*****",password="******",nonce="5ae ab8af7e8e241f07ea0c3868584f12", opaque="17051842362549", uri="/rets/login">
