Using the fake web server code from the Perl cookbook (p691) I compared the request headers for the 2 methods. Here are the results
GET /index.htm HTTP/1.1
Connection: TE, close
Host: localhost:8989
TE: deflate,gzip;q=0.3
User-Agent: libwww-perl/5.69
GET /index.htm HTTP/1.1
Cache-Control: no-cache
Pragma: no-cache
Accept: text/*, image/jpeg, image/png, image/*, */*
Accept-Charset: iso-8859-1, utf-8;q=0.5, *;q=0.5
Accept-Encoding: x-gzip, gzip, identity
Accept-Language: en
Host: localhost:8989
User-Agent: Mozilla/5.0 (compatible; Konqueror/3; Linux)
I'm no expert but I suspect it is something to do with the Transfer-Encoding and/or output-filtering caused by the way Apache is configured. I noticed wwww.yahoo.com has no leading spaces even in the browser.
