How to ignore case sensitiveness of jquery ajax call url

[Jack Hard]

i am working on Asp.net 3.5 project and i am calling a webservice by ajax call

$.ajax({
type: "Post",
contentType: "application/json; charset=utf-8",
url: "WebService/DefaultPage.asmx/GetTours",
dataType: "json",
success: function (data) {
Home.ReadTours(data);
},
error: function (result) {
$('.load-3').hide();
}
});

working fine..

but when i change the url to lowercase..

url: "webservice/defaultpage.asmx/gettours",

its not working.

Is this Jquery Ajax URL is case sensitive and is there any by i can ignore case sensitiveness of ajax url..
