SAP Web Dispatcher has router redirecting same web host

[collinjona]

Dear all,

I have two server :

1 non sap server hosted srv.exemple.fr with port 443

2 sap system hosted ex.myapp.exemple.fr on port 44300

I have setup the web dispatcher with the below configuration:

icm/server_port_0 = PROT=ROUTER,PORT=443, EXTBIND=1
icm/server_port_1 = PROT=HTTP,PORT=80, EXTBIND=1
icm/server_port_2 = PROT=HTTPS,PORT=8443
exe/icmbnd = /usr/sap/WDP/W00/exe/icmbnd
icm/HTTP/logging_00 = PREFIX=/, LOGFILE=access_log-%d-%m-%y_%h:%t:%s,LOGFORMAT=%t %h %u - "%r2" %s %b %L %a %r1


#-----------------------------------------------------------------------
# SAP Web Dispatcher Administration
#-----------------------------------------------------------------------
icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=$(DIR_DATA)$(DIR_SEP)icmandir,AUTHFILE=$(icm/authfile)
#-----------------------------------------------------------------------
# Start webdispatcher
#-----------------------------------------------------------------------
_WD = $(rdisp/workdir)/wd.sap$(SAPSYSTEMNAME)_$(INSTANCE_NAME)
Execute_02 = local rm -f $(_WD)
Execute_03 = local ln -s -f $(DIR_EXECUTABLE)/sapwebdisp$(FT_EXE) $(_WD)
Restart_Program_00 = local $(_WD) pf=$(_PF)
SETENV_05 = SECUDIR=$(DIR_INSTANCE)/sec






wdisp/system_0 = SID=EXT, EXTSRV=https://srv1.exemple.fr, SRCSRV=srv1.exemple.fr:443, SRCURL=/
wdisp/system_1 = SID=DEV, MSHOST=dev,MSPORT=8100, SRCSRV=ex.myapp.exemple.fr:443;mb.myapp.exemple.fr:443, SRCURL=/




icm/HTTP/mod_0 = PREFIX=/, FILE=/sapmnt/WDP/profile/mod_rules.txt

the mod_rules.txt files contains the below configuration:

  if %{HTTP_HOST} regimatch "ext.myapp.exemple.fr"
     SetHeader x-sap-webdisp-target-sid DEV [break]
  if %{HTTP_HOST} regimatch "srv1.exemple.fr"
     SetHeader x-sap-webdisp-target-sid EXT [break]
  if %{HTTP_HOST} regimatch "ex.myapp.exemple.fr"
     SetHeader x-sap-webdisp-target-sid DEV [break]

The main problems is when I want to go to srv1.exemple.fr it's ok

when I want to go ex.myapp.exemple.fr I'm redirected to the web server hosting srv1.exemple.fr

So all my URL are redirect to the same server and not distributed.

My sap web dispatcher is 7.45

Any idea why ? I see nothing wrong in my log file

Thanks and regards

Hi Christiano,

Thanks for your answer.

I set the trace level to 2 and see the below information when executing the mod_rules files

IF "%{HTTP_HOST}"->"sapwdp.exemple.fr", 

"sapwdp.exemple.fr" is the dns of my sap web dispatcher

any idea why the HTTP_POST is changed by it ?
