How to send POST request for request payload data?

[aseagle]

C++ and libcurl are being used.


How do I post "request payload" data?
FYI I did ask this on stack overflow but I really need a response ASAP so I apologize in advance. And yes I have googled this however the examples I find seem to rely on the content type being "JSON", and it doesn't seem like that is the case here.

Response Headers:

Content-Type: text/html; charset=utf-8

Request Headers:

Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryG82cUGis7lmfHL19

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

Request Payload:

Content-Disposition: form-data; name="__VIEWSTATE" ------WebKitFormBoundaryG82cUGis7lmfHL19 Content-Disposition: form-data; name="ctl00$Pager" ------WebKitFormBoundaryG82cUGis7lmfHL19 Content-Disposition: form-data; name="__EVENTTARGET" ctl01$TC$BBD_ISSUE_RPTLink ------WebKitFormBoundaryG82cUGis7lmfHL19 Content-Disposition: form-data; name="__EVENTARGUMENT" ------WebKitFormBoundaryG82cUGis7lmfHL19 Content-Disposition: form-data; name="__EVENTVALIDATION" /wEWFAL+raDpAgLUy9G7AwLH6/qKCgKDnbntDgLH0vqJCAK5l5O1CQK42rCNBQKM4fNgAufEqeEHAoe/ytQJAvvQvU4C96OJow0C3YnIpgsC0a3s6A0CroaZiAYC28K51g4CpLPr/gcC46L8ww0Cq83cug4C0+nlwAzDcbaDFsCek7cLKaKs8kyafpbT3w== ------WebKitFormBoundaryG82cUGis7lmfHL19--
