$req = New-Object Chilkat.HttpRequest

# Loads the HTTP request object from a URL
$req.SetFromUrl("https://www.youtube.com/watch?v=fAZdTchQePc&t=45s")

# The verb will be "GET"
$("verb = " + $req.HttpVerb)
# The path will be "/watch"
$("path = " + $req.Path)

# The output of this loop will be
# 0) v: fAZdTchQePc
# 1) t: 45s

$numParams = $req.NumParams

    $([string]$i + ") " + $req.GetParamName($i) + ": " + $req.GetParamValue($i))
}

# View the request that would be sent if SynchronousRequest is called.
# The HTTP request will be a GET that looks like this:
# 
#     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
#     Host: domain
# 
# Note: The HOST header will automatically get filled in with the actual domain when SynchronousRequest is called.

$($req.GenerateRequestText())

# We can add additional params
$req.AddParam("artist","Richard Bona")
$req.AddParam("musicType","Jazz")
$req.AddParam("festival","Estival Jazz Lugano")
$req.AddParam("year","2008")

# Now examine the request that would be sent
# 
#     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
#     Host: domain
# 
$($req.GenerateRequestText())

# We can remove a parameter:
$req.RemoveParam("t")
$($req.GenerateRequestText())

# What happens if we change the request from a GET to a POST?
$req.HttpVerb = "POST"
# The request will now look like this:
# 
#    POST /watch HTTP/1.1
#    Host: domain
#    Content-Length: 93
#    
#    v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
# 
$($req.GenerateRequestText())

# What happens if we make it a multipart/form-data?
$req.ContentType = "multipart/form-data"
# Now the POST looks like this:
#    
#    POST /watch HTTP/1.1
#    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
