There are several filter init parameters which can be used to configure the behaviour of the SSI filter.
contentType – A regex pattern that must be matched before SSI processing is applied. When crafting your own pattern, don’t forget that a mime content type may be followed by an optional character set in the form “mime/type; charset=set” that you must take into account. Default is “text/x-server-parsed-html(;.*)?”.
debug – Debugging detail level for messages logged by this servlet. Default 0.
expires – The number of seconds before a page with SSI directives will expire. Default behaviour is for all SSI directives to be evaluated for every request.
isVirtualWebappRelative – Should “virtual” SSI directive paths be interpreted as relative to the context root, instead of the server root? Default false.
allowExec – Is the exec command enabled? Default is false.
