Azure AG WAF file upload

Question

We need to upload a file with size is about 100MB and got blocked by Application Gateway WAF, we use the "file upload" method which is described here: https://learn.microsoft.com/en-us/azure/web-application-firewall/ag/application-gateway-waf-request-size-limits

"Only requests with Content-Type of multipart/form-data are considered for file uploads. For content to be considered as a file upload, it has to be a part of a multipart form with a filename header. For all other content types, the request body size limit applies."

We addeds Headers

Content-Type: multipart/form-data

Filename: example.txt

But the content was still treated as a request body and limited by 2MB max size...

How do make a proper request for "file uploads"? any example code will be helpful.

thank you!
