* Function : execute_client_body_filters
*
* Description : Executes client body filters for the request that is buffered
- * in the client_iob. Upon success moves client_iob cur pointer
- * to the end of the processed data.
+ * in the client_iob. The client_iob is updated with the filtered
+ * content.
*
* Parameters :
* 1 : csp = Current client state (buffers, headers, etc...)
* 2 : content_length = content length. Upon successful filtering
* the passed value is updated with the new content length.
