Nimbostratusredirection and cookies
Please help with this if you can... any suggestions about solving this issue are welcomed. Thank you for your time.
If a user from x ip address(es) connects to http://almstage.domain.com they are redirected to a page telling them to use a different method of accessing this resource (windows terminal servers), after 30 seconds the page redirects back to http://almstage.domain.com/qcbin/ and can access the webpage like anyone else for x amount of time. If a user from any ip type in http://almstage.domain.com they will automagically get redirected to http://almstage.domain.com/qcbin/.
http://almstage.domain.com/qcbin/index.jsp -- is where this app lives
http://almstage.domain.com/qcbin/WTSannouncement.htm - this is where the redirect page lives.
When I try the following code I get a redirection loop and a cookie is never set... if I comment out HTTP::redirect "http://almstage.domain.com/qcbin/WTSannouncement.htm" under the HTTP_response the cookie gets set and everything works fine. The code probably has redundancy when it comes to the cookie timeout.
when CLIENT_ACCEPTED {
Settings
set need_cookie0
set base_time [clock seconds]
set session_timeout 600
set cookie "cttiverify"
}
when HTTP_REQUEST {
log local0. "Redirect_cookie rule active"
if { [IP::client_addr] equals "10.60.249.237" } {
log local0. "matched ip"
if { [HTTP::cookie exists $cookie]} {
log local0. "we have a cookie"
set cookie_time [HTTP::cookie $cookie]
if {[expr $base_time - $cookie_time] > $session_timeout } {
set need_cookie1
log local0. "cookie is old - set cookie is $need_cookie"
HTTP::cookie insert name $cookie value $base_time path "/"
HTTP::redirect "http://almstage.domain.com/qcbin/WTSannouncement.htm"
}
else {
log local0. "all test passed"
set need_cookie0
pool RtpAlmStageAS
}
}
else {
set need_cookie1
log local0. "don't have a cookie - set cookie is $need_cookie"
HTTP::cookie insert name $cookie value $base_time path "/"
HTTP::redirect "http://almstage.domain.com/qcbin/WTSannouncement.htm"
}
}
elseif { [HTTP::uri] contains "/qcbin"} {
pool RtpAlmStageAS
}
else {
HTTP::redirect "http://almstage.domain.com/qcbin/"
}
}
when HTTP_RESPONSE {
log local0. "http response - $need_cookie"
if { $need_cookie equals 1 } {
log local0. "inserting cookie in response - set cookie is $need_cookie"
HTTP::cookie remove $cookie
HTTP::cookie insert name $cookie value $base_time path "/"
HTTP::cookie expires $cookie 600 relative
HTTP::redirect "http://almstage.domain.com/qcbin/WTSannouncement.htm"
}
}
Thanks,

Hi Dendy,
If you want to set a cookie in a redirect you can use HTTP::respond:http://devcentral.f5.com/wiki/default.aspx/iRules/http__respond when HTTP_REQUEST { set ckname "app" set ckvalue "893" set cookie [format "%s=%s; path=/; domain=%s" $ckname $ckvalue ".domain.org"] HTTP::respond 302 Location "http://www.domain.org" "Set-Cookie" $cookie }
