Filter Name

[Thambi Rajah]

Hello Ranchers,
I like to know whether filter-name element can have space(Secure Name)as below:

<filter>
   <filter-name>Secure Name</filter-name>
   <filter-class>filter.FilterServlet</filter-class>
</filter>
<filter-mapping>
   <filter-name>Secure Name</filter-name>
   <url-pattern>*.jsp</url-pattern>
</filter-mapping>  

Thanks in advance,
Thambi
