What would happen if two IIS redirect to each other? -

what happen if, put 301 redirect in iis 6 1 web site (a) redirect site (b), same page, having iis 7 site (b), redirect old page in (a).

are going cause infinite , forth redirect? or going cancel each other out?

for example:

(a) iis6: www.example.com/123 redirect www.example.net/abc (b) iis7: www.example.net/abc redirect www.example.com/123

http 301 status code not request. browsers rather web server, web server not "know" you've been redirected back. browsers¹ should detect redirect loop , stop error.

_{1. know true chrome , relatively recent ff, no idea ie...but i'd imagine detected.}
