404 Error when sending Servlet request to IIS Dispatcher

Question

I am configuring dispatcher in IIS. The dispatcher works fine for all pages but servlet.
I can send request to myServlet through CQ original url successfully (http://localhost:4503/myServlet). However when I browse myServlet through IIS (http://192.168.0.1/myServlet), 404 error occurs.
Following is more info:
CQ version: 5.5
Dispatcher version: 4.1.3
IIS version: 7.5
message in dispatcher log:
Dispatcher initializing (build 4.1.3)
farms[myApp].homepage = /content/myApp.html
farms[myApp].cache.docroot = c:\inetpub\wwwroot
Dispatcher initialized (build 4.1.3)
Found farm myApp for 192.168.0.1
checking [/myServlet]
no cache due to missing extenson in uri: /myServlet
cache-action for [/myServlet]: NONE
Filter rejects GET /myServlet HTTP/1.0
Can anyone help? Thanks in advance.

The last message from the dispatcher log file you provided already points in the right direction: You need to change the filter definition in your dispatcher configuration to allow request to your serlvet. For example, you could provide an explicit configuration entry for your servlet such as the following:
/filter
   /0001 { /type "deny"  /glob "*" }
   /0010 { /type "allow" /glob "/myServlet" }
Or follow a more generic approach, where you use a common path for all your servlets (e.g. "/bin") and allow requests to this path in your dispatcher configuration:
/filter
  /0001 { /type "deny"  /glob "*" }
  /0010 { /type "allow" /glob "/bin/*" }
