i have tried to load cache disk mod on ibm http server 8.5.5.12 and while restarting im getting the below error ]$ sudo ./apachectl stop httpd: Syntax error on line 170 of /appl/WEB/IBM/HTTPServer/conf/httpd.conf: Cannot load /appl/WEB/IBM/HTTPServer/modules/mod_disk_cache.so into server: /appl/WEB/IBM/HTTPServer/modules/mod_disk_cache.so: undefined symbol: ap_cache_cacheable_hdrs_out any suggestion would be helpful.
You should ask IBM for support of their distribution. But this particular symptom is already well documented on a basic web search. Load mod_cache first.
