Hello,
I see 2 issues with the following line:
icm/http/mod_22 = PREFIX=/jlq,FILE=/usr/sap/<SID>/webdispatcher/mod_rules1.txt
from webdispatcher admin I see that the prefix is always displayed as "/". Never with any prefix I want to use.
Also, regardless of the index 22, 2, 3, etc, WD always displays it as mod_1.
As you can see below, the rewrite rules are to strip off the prefix but the mod handler is never invoked as the URL prefix handler can never be set properly.
