Package org.apache.catalina.ssi

This package contains code that is used by the SsiInvoker.

This class consists of SsiMediator.java which works as a mediator between the different SsiCommands. To add a command you have to implement the SsiCommand interface and extend the SsiMediator. Commands currently implemented are

• SsiConfig - Implementation of the NCSA command Config i.e. <!--#config errmsg="error?"-->
• SsiEcho - Implementation of the NCSA command Echo i.e. <!--#echo var="SERVER_NAME"-->
• SsiExec - Not implemented
• SsiFlastMod - Implementation of the NCSA command flastmod i.e. <!--#flastmod virtual="file"-->
• SsiFsize - Implementation of the NCSA command fsize i.e. <!--#fsize file="file"-->
• SsiInclude - Implementation of the NCSA command Include i.e. <!--#config virtual="includefile"-->
