Safari iframe cookie workaround

Safari by default discards cookies set in an iframe unless the host that's serving the iframe has set a cookie before, outside the iframe. Safari is the only browser that does this.

The 10k foot view

In order to get around the issue, the parent (src) and child/iframed/remote (dest) site have to work together, if the source site only wants users to access the destination via the iframe and can't assume that the user has visited the destination host before.

/**
 * PHP's curl extension won't let you pass in strings as multipart file upload bodies; you
 * have to direct it at an existing file (either with deprecated @ syntax or the CURLFile
 * type). You can use php://temp to get around this for one file, but if you want to upload
 * multiple files then you've got a bit more work.
 * 
 * This function manually constructs the multipart request body from strings and injects it
 * into the supplied curl handle, with no need to touch the file system.
