A question of HTTP path on Web Service :(

[kailan_cn]

I refer to the document (http://wiki.lazarus.freepascal.org/Web_Service_Toolkit) I wrote a simple WebService program.
But,I find a question,One binding property in the type-lib confuses me,For example:
Bingings->
    -UserServiceBinging
             -RPC
             -http://127.0.0.1:8000/services/UserService


In the 'service' part of the problem is in the path.
Client program was fail when I modify 'service' to other,for example:
http://127.0.0.1/svr/UserService

Client program was success again when I modify to 'services'.

Can I modify name of path as my idea ?
