[umesh_vid1080]

Hello All ,

I have issues with Http 80 migration  from CSS to ACE . i have implemented layer 4 policy match but we have issues with application . It do not work properly when i implmenet below ACE configuration .

Any help would be highly appreciated .  Thanks in Advance !

CSS Config :

service s0adcmer1

  ip address 192.168.1.10

  keepalive type tcp

  keepalive port 80

  active

service s0adcmer2

  ip address 192.168.1.11

  keepalive type tcp

  keepalive port 80

  active

owner WEB

  content webservers

    add service s0adcmer1

    vip address 192.168.1.20

    add service s0adcmer2

    balance leastconn

    protocol tcp

    port 80

    url "/*"

    advanced-balance arrowpoint-cookie

    arrowpoint-cookie name web

    arrowpoint-cookie browser-expire

    active

ACE Config :

rserver host s0adcmer1

  inservice

  ip address 192.168.1.10

exit

rserver host s0adcmer2

inservice

ip address 192.168.1.11

exit

serverfarm host WEB

  predictor leastconns

  probe PROBE_TCP_HTTP

  rserver s0adcmer1

    inservice

  rserver s0adcmer2

    inservice

exit

sticky http-cookie  web  webservers_STICKY

  cookie insert browser-expire

  replicate sticky

  serverfarm WEB

exit

class-map match-any webservers_CLASS

  2 match virtual-address 192.168.1.20 tcp eq  http

exit

policy-map type loadbalance first-match webservers_POLICY

  class class-default

    sticky-serverfarm webservers_STICKY

exit

policy-map multi-match POLICY

  class webservers_CLASS

    appl-parameter http advanced-options CASE_PARAM

    loadbalance vip inservice

    loadbalance vip icmp-reply active

    loadbalance policy  webservers_POLICY

    nat dynamic 10 vlan 20

exit

After i implemeted above config in ACE we got  issues  .

Initial URL is http://192.168.1.20 But when user go to below url after initially login with http://192.168.1.20  . The next  window  do not pop-up . 

     http://192.168.1.20/web/WebUI/Popup/PopupFrame.aspx

What is suitable layer 7 policy to resolve this issues ?

Is below Layer 7 policy resolve the issues ?

class-map type http loadbalance match-any webservers_CLASSURL

match http url    .*

exit

What does live http header show ? Any trace available ?

[umesh_vid1080]

No trace right now .

I have updated the config with below L7 policy

class-map type http loadbalance match-any webservers_CLASSURL

match http url    .*

And increase the header-maxparse which resolve the issues  , But still one user not able to access the link . When he tries to access the link we are seeing the increment in  "  Static parse errors   " 

user is able to telnet on port 80 on VIP .

sh running-config parameter-map :

parameter-map type http CASE_PARAM

  case-insensitive

  persistence-rebalance

  set header-maxparse-length 8192

  length-exceed continue
