I am not sure what you meant by "In Foo" but your PUT request quoted
above is missing a body. See RFC 2616 or google for PUT request examples.

If you are using squidclient, then according to documentation, the
command to send a PUT request containing Foo.txt file to the origin
server located at Bar URL is

   squidclient -P Foo.txt Bar

However, it is not clear what a PUT request gives you since Squid cannot
cache PUT request bodies.

HTH,
