ServerA -> Basic Authentication
ServerB -> Windows Integrated
You must turn on impersonation in ServerA web.config:
<authentication mode="Windows" />

<identity impersonate="true"></identity>

If you have a code like Response.Redirect(http://serverB/default.aspx) in a
ServerA page, IIS (automatically) succesfully authenticate the user (the
user must be a valid user for both serverA and ServerB) and you don't need
to write any additional code.

FYI, extracted from your original post:
...access a page on Webserver B (which uses basic
authentication), but I don't want them to have to login again ...
