I am using my website to check the broken links with Xenu and it is not interpreting the server side redirection properly.
I have build my website using asp.net and used server side direction as follows Client is redirected from this page
http://mysite.com/ordermanagement/ordersequence/OrderFormRedirector.aspx
to /signup/newclientsignup.aspx?pt=0&pkc=0&pkt=0 from server side which rendered as
http://mysite.com/signup/newclientsignup.aspx?pt=0&pkc=0&pkt=0
but Xenu interpret it as follows
http://mysite.com/ordermanagement/ordersequence/%2fsignup%2fnewclientsignup.aspx%3fpt=0&pkc=0&pkt=0
