http.request.body.multipart.content_transfer_encodings

http.request.body.multipart.content_transfer_encodingsArray<Array<String>>

List of Content-Transfer-Encoding headers for each part in the multipart body.

Requires a Cloudflare Enterprise plan.

Example value:

[["quoted-printable"], ["base64"]]

Example usage:

any(http.request.body.multipart.content_transfer_encodings[*][0] == "binary")

Caution

All http.request.body.* fields (except http.request.body.size) handle a given maximum body size, which varies per plan. For Enterprise customers, the maximum body size is 128 KB. For other paid plans, the limit is lower by default — reach out to your account team or to Cloudflare Support to increase the limit. For users in the Free plan, the limit is 1 MB.

You cannot define expressions that rely on request body data beyond the maximum size set for your plan. If the request body is larger, the body fields will contain a truncated value and the http.request.body.truncated field will be set to true. The http.request.body.size field will contain the full size of the request without any truncation.

The maximum body size applies only to the values of HTTP body fields — the origin server will still receive the complete request body.
