Web OS 10.0 Application GuideChapter 8: Application Redirection n 215212777-A, February 2002Excluding Noncacheable SitesSome Web sites provide content that is not well suited for redirection to cache servers. Suchsites might provide browser-based games or applications that keep real-time session informa-tion or authenticate by client IP address.To prevent such sites from being redirected to cache servers, create a filter which allows thisspecific traffic to pass normally through the Web switch. This filter must have a higher prece-dence (a lower filter number) than the application redirection filter.For example, if you wished to prevent a popular Web-based game site on subnet 200.10.10.*from being redirected, you could add the following to the previous example configuration:>> # /cfg/slb/filt 1 (Select the menu for filter 1)>> Filter 1# dip 200.10.10.0 (To the site’s destination IP address)>> Filter 1# dmask 255.255.255.0 (For entire subnet range)>> Filter 1# sip any (From any source IP address)>> Filter 1# proto tcp (For TCP traffic)>> Filter 1# dport http (To an HTTP destination port)>> Filter 1# sport any (From any source port)>> Filter 1# action allow (Allow matching traffic to pass)>> Filter 1# ena (Enable the filter)>> Filter 1# ../port 5 (Select SLB port 5)>> SLB port 5# add 1 (Add the filter to port 5)>> SLB port 5# ../port 6 (Select SLB port 6)>> SLB port 6# add 1 (Add the filter to port 6)>> SLB port 6# apply (Apply configuration changes)>> SLB port 6# save (Save configuration changes)
