# See Global Unlock Sample for sample code.

# Insert your AWS keys here:

# User-defined metadata are name/value pairs, and are added to the HTTP request header.
# Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
# Note that Amazon S3 stores user-defined metadata keys in lowercase.

# For example, to add genus=Hippocampus, we do this:
$http->SetRequestHeader("x-amz-meta-genus","Hippocampus");

# Add a few more user-metadata key pairs.
$http->SetRequestHeader("x-amz-meta-species","big-belly seahorse");
$http->SetRequestHeader("x-amz-meta-habitat","shallow tropical and temperate waters");
