The Edge SWG has a specific limit for the HTTP header.

• Header count = 1,000
• Header Length = 100,000

The Edge SWG indicates that event message when the HTTP response header exceeds the specification limit.

You can change the default value by CPL; see the CPL reference guide.

response.raw_headers.max_count(unsigned-integer)
response.raw_headers.max_length(unsigned-integer)

[Note]

Edge SWG presents the exception Response Error(invalid_response) and blocks this response if the HTTP response header exceeds.

This is a sample exception page.
