 H5: Cacheable Queries
 
 A LDAP search query is cacheable when its filter matches one of the
-templates as defined in the "proxyTemplate" statements and when it references
+templates as defined in the "pcacheTemplate" statements and when it references
 only the attributes specified in the corresponding attribute set. 
 In the example above the attribute set number 0 defines that only the
 attributes: {{EX:mail postaladdress telephonenumber}} are cached for the following
