I have little experience with lower level http, and I am curious about a situation which I've come across.
I was monitoring http traffic with HttpWatch, and noticed that an IIS asp.net server on submitting an .aspx login form returns a 200 OK response, after which the browser redirects to a site inner (authenticated) page. The login response contains no redirection headers (no 302), and the content of the response is plain text: "
22|pageRedirect||/Official/Default.aspx|" (containing the relative redirection path).
If anyone could clear things up about how the redirection comes about, I would be grateful.
