PathParam how to set Regex to allow URL?

Question

I am using @PathParam and the request format is like this,

@Path("/XXX/XXX/{testvariable:[\\s\\S]+}")

Here, testvariable can take values like http://google.com/myname.txt, 191.123.122.333 or in short a String with any special characters.

The regex that I used doesn't seem to allow the value "http://google.com/myname.txt" for this.

I get response saying, ".No operation matching request path". Please help.

Thanks in advance.
