Web dispatcher and HTTPS forwarding

[Former Member]

Hi!

I've set up the web dispatcher for our e-business scenario and I've run into some problems with the SSL protocol.

I found some blogs

/people/prakash.singh4/blog/2005/08/16/how-to-setup-webdispatcher-to-load-balance-portal-in-a-clustered-environment

/people/gregor.wolf3/blog/2005/11/07/setup-sap-web-dispatcher-with-url-filter-on-suse-linux-90

and this page at help.sap.com

<a href="http://help.sap.com/saphelp_nw04/helpdata/en/b2/032a3c2ffdc62fe10000000a114084/content.htm">Example: Profile File of a SAP Web Dispatcher</a>

It is quite simpel to set it up for HTTP, but HTTPS is not working.

My profile looks like this

# Profile generated by sapwebdisp bootstrap

# unique instance number
SAPSYSTEM = 1

# add default directory settings
DIR_EXECUTABLE = .

DIR_INSTANCE = .

# Accessibility of Message Servers
rdisp/mshost = drcrm002
ms/http_port = 8100

# SAP Web Dispatcher Parameter
wdisp/auto_refresh = 120
wdisp/max_servers = 100

wdisp/shm_attach_mode = 6

# configuration for default scenario (medium size)
icm/max_conn      = 500
icm/max_sockets   = 1024
icm/req_queue_len = 500
icm/min_threads   = 10
icm/max_threads   = 50
mpi/total_size_MB = 80

#maximum number of concurrent connections to one server
wdisp/HTTP/max_pooled_con = 500
wdisp/HTTPS/max_pooled_con = 500

# Parameters for the HTTPS Routing
wdisp/HTTPS/dest_logon_group        = HTTPS
wdisp/HTTPS/max_client_ip_entries   = 100000
wdisp/HTTPS/sticky_mask             = 255.255.255.0

# SAP Web Dispatcher Ports
icm/server_port_0 = PROT=HTTP,PORT=80
icm/server_port_1       = PROT=ROUTER,PORT=443

# SAP Web Dispatcher Web Administration
icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=./admin,AUTHFILE=icmauth.txt

When I go to http://drsaptest/b2c/b2c/init.do it works fine, but when I go to https://drsaptest/b2b/b2b/init.do I get the error message that the webpage can not be displayed.

Is there something wrong in the profile or do I have to do something on the CRM machine as well?

//edit

Found this in the trace file

[Thr 2072] Wed Nov 01 15:15:24 2006 
[Thr 2072] *** ERROR => RoutePlgAttachToNewServer: IcrAttachToServer(10.10.1.24) for group HTTPS: rc=13 [route_plg.c 1153]
