Yes, you can set HTTP headers directly from the process. To do that, you
have two options:
1. you can use the HTTP-binding extensions and bind a message part to a
header. [1] In that case, simply assign your part with the desired value,
and ODE will set the HTTP header it is bound to.
2. or you can use the "<to header>" assignment:
<assign>
<copy>
<from>...</from>
<to variable="your_msg" header="your_header"/> #
your_header being an HTTP header (standard or not)
</copy>
</assign>

So for basic auth, what you would have to do is to set the Authorization
header. The disappointing part is that you have to pass the credentials
already base64-encoded. Something like 'Basic Zm9vbGtqZGpoZmxramhzZGZraAo='
Not really neat.
But I'm about to contribute a specific mechanism for authentication. You
should be able to create a message part named WWW-Authentication containing
an element similar to:
<xs:complexType name="credentialType">
<!-- accepted scheme are Basic and Digest -->
<xs:attribute name="scheme" type="xs:string" default="server-decide" />
<xs:attribute name="username" type="xs:string" />
<xs:attribute name="password" type="xs:string" />
</xs:complexType>
<xs:element type="rest_connector:credentialType" name="credentials" />

By the way, comments are welcome on this.

All HTTP response headers are set on the response message. So you can assign
from them easily.
For instance:
<assign>
<copy>
<from variable="responseMsg" header="Content-Language"/>
<to variable="nextRequestMsg" header="Accept-Language"/>
</copy>
<copy>
<from variable="responseMsg" header="Last-Modified"/>
<to>$timestamp</to>
</copy>
</assign>
I hope it helps.
