The portion of the Profile spec you refer to is 
talking about the Browser SSO profile -- in that profile of SAML you MUST 
NOT use an HTTP-Redirect (you can, of course, use an Artifact via HTTP-Redirect 
to represent the response).  That doesn't mean there aren't other profiles 
of SAML that could use the HTTP-Redirect for a response 
message.

 

In fact, the example in the Bindings is of an SLO profile 
message.

  Using HTTP Redirect to send a Response? Profiles spec says no. Bindings spec

Hi 
  Folks,

  
 

  
In section 4.1.2, bullet 5 of the 
  Profiles specification it says:  “The HTTP Redirect binding MUST NOT be 
  used [for sending a Response to a Service Provider], as the response will 
  typically exceed the URL length permitted by most user 
  agents”.

  
 

  
In the Bindings specification, in 
  3.4.8 it shows an example of using HTTP Redirect to send a Response to a 
  Service Provider.

  
 

  
So, the Profiles spec says that 
  HTTP Redirect must not be used, whereas the Bindings spec says that HTTP 
  Redirect can be used.  Which is correct?
