Hi Shuai,
The error i am getting in the web dispatcher log.SO i believe the block is in the WD itself.
I am using a sub-domain in the URL for differentiating the URL for each server.
ie,
EXTURL : https://xxxxxxxx.yyyyy.COM:443/sapclouddev/sap/bc/srt/idoc?sap-client=220
INTURL: https://xxxxxxxx.yyyyy.COM:44300/sap/bc/srt/idoc?sap-client=220
For attaining this following are the parameters and values set in in the web dispatcher
icm/server_port_0 = PROT=HTTP,HOST=localhost,PORT=81$$
icm/server_port_1 = PROT=HTTPS,HOST=xxxxxxxx.yyyyy..com,PORT=443,ACLFILE=\\xxxdsp00\sapmnt\XXX\W00\sec\ACL.txt
icm/HTTP/admin_0 = PREFIX=/sap/admin,DOCROOT=$(DIR_DATA)$(DIR_SEP)icmandir,AUTHFILE=$(icm/authfile),PORT=81$$;443
wdisp/group_info_protocol = https
wdisp/url_map_protocol = https
wdisp/ping_protocol = https
wdisp/ssl_encrypt = 0
#settings for client certificate handling
icm/HTTPS/verify_client = 1
icm/HTTPS/forward_ccert_as_header = true
wdisp/ssl_auth = 0
wdisp/system_0 = SID=DEV, MSHOST=xxxxxxxx.yyyyy.corp, MSPORT=8100, SRCURL=/sapclouddev
icm/HTTP/auth_0 =PREFIX =/sapclouddev,PERMFILE= \\ergdsp00\sapmnt\EWD\W00\sec\perm.txt (Full perm for now)
icm/HTTP/mod_0 =PREFIX=/sapclouddev,FILE=\\xxxdsp00\sapmnt\XXX\W00\sec\actionfile.txt
action file
RegIRewriteUrl /sapclouddev/sap(.*) /sap$1 [qsreplace]
Please let me know whether there is any mistake in the above config
