Websites fail to display properly via Netscaler VPN after upgrade where they worked fine before.
Legacy syntax to set the pwcount cookie at the Netscaler Gateway Vserver may be causing this issue.
Bad syntax:
add rewrite action RW_ACT_DEL_2ND_PWD insert_http_header Set-Cookie ("pwcount=\"+1")
This may be causing the Netscaler to set a bad cookie. If this syntax is used in the config, you would see the cookie being used as pwcount="+1 where it should read pwcount=1
