/**
* Define the module name, MUST BE the same as .so file name;
* i.e., if MNAME is testmodule, then the .so must be testmodule.so.
*
* How to test this sample
* 1, Build the module, put reqobservmodule.so in $LSWS_HOME/modules
* 2, Create a file with the bad words.
* 3, Run curl and upload the file and access a dynamically generated page,
* curl -F "file=@/home/.../filewithbadwords" http://localhost:8088/phpinfo.php
* 4, If filewithbadwords contain at least one word in blockWords,
* will get 403, otherwise will get 200
