javascript - PDF.js CORS issue -


i'm having issue pdf.js , cors configuration.

from domain i'm loading pdf.js iframe file parameter (full path server, return pdf document). pdf.js create request server @ domain b origin: domain a. server @ domain b returns pdf document header access-control-allow-origin: domain a, far good.

in network tab see request server, returning 200 status ok, pdf.js throwing error unexpected server response (0) while retrieving pdf <url>.

the question is, what's going on here, cors seems ok, can't more info pdf.js real reason pdf failing load. there encountered same?

finally found problem. server not passing access-control-allow-credentials: true header response, needed (xhr request sent xhr.withcredential).

cors working properly.
