CDN Edge Purge
There are two methods for purging content from the edge: One for purging individual objects, one for purging entire containers.

Object Purge

To purge a given object "foo.txt" in the container "bar", send the following to the X-CDN-Management-URL:

DELETE /v1/<account-id>/bar/foo.txt HTTP/1.1
Host: <X-CDN-Management-URL>
X-Auth-Token: <auth-token>
X-Purge-Email: user@domain.com
That will purge that object from Akamai, and send an email to user@… when it's done. Note, the email address is optional, or can be a comma separated list of them if you want to notify more than one person.

Container Purge

To purge an entire container named "bar", send the following to the X-CDN-Management-URL:

DELETE /v1/<account-id>/bar HTTP/1.1
Host: <X-CDN-Management-URL>
X-Auth-Token: <auth-token>
X-Purge-Email: user@domain.com
That will purge all objects in that container from Akamai, and send an email to user@… when it's done (might take a while, be patient). Note, the email address is optional, or can be a comma separated list of them if you want to notify more than one person.
