I am curl-ing an endpoint that does a redirection to an S3-bucket.

I must pass some large headers to my request which fails because the max header size is exceeded:

<?xml version="1.0" encoding="UTF-8"?>
<Error>
   <Code>RequestHeaderSectionTooLarge</Code>
   <Message>Your request header section exceeds the maximum allowed size.</Message>
   <MaxSizeAllowed>8192</MaxSizeAllowed>
   <RequestId>AP394DD4D4F133</RequestId>
   <HostId>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</HostId>
</Error>

Is there a way to tweak this at the S3 level & increase the maximum allowed header size?

So it is directly downloading from the S3 bucket? Or is this going via API gateway etc.? How are you exactly downloading(?) this file – Ermiya Eskandary Mar 31 '22 at 11:54
It is not downloading. Just a GET request with huge headers – pkaramol Mar 31 '22 at 13:09
GET request to what? – Ermiya Eskandary Mar 31 '22 at 18:19
To the bucket hosting a static site – pkaramol Apr 18 '22 at 13:34
Is this still an issue? – Ermiya Eskandary May 02 '22 at 08:09
