Fixes#7407
Add comprehensive documentation and example configuration for using
nginx as a reverse proxy with SeaweedFS S3 API while maintaining AWS
Signature V4 authentication compatibility.
Changes:
- Add docker/nginx/README.md with detailed setup guide
- Add docker/nginx/s3-example.conf with working configuration
- Update docker/nginx/proxy.conf with important S3 notes
The documentation covers:
- Critical requirements for AWS Signature V4 authentication
- Common mistakes and why they break S3 authentication
- Complete working nginx configurations
- Debugging tips and troubleshooting
- Performance tuning recommendations
Fix IPv6 host header formatting to match AWS SDK behavior
Follow-up to PR #7403
When a default port (80 for HTTP, 443 for HTTPS) is stripped from an
IPv6 address, the square brackets should also be removed to match AWS
SDK behavior for S3 signature calculation.
Reference: https://github.com/aws/aws-sdk-go-v2/blob/main/aws/signer/internal/v4/host.go
The AWS SDK's stripPort function explicitly removes brackets when
returning an IPv6 address without a port.
Changes:
- Update extractHostHeader to strip brackets from IPv6 addresses when
no port or default port is used
- Update test expectations to match AWS SDK behavior
- Add detailed comments explaining the AWS SDK compatibility requirement
This ensures S3 signature validation works correctly with IPv6 addresses
behind reverse proxies, matching AWS S3 canonical request format.

This change is caching HMAC hashers for repeated use in subsequent
requests and chunks, so they don't have to be initialized from
scratch every time.
On my local computer this gives me ~5-6 times faster signature
calculation and ~5-6.5% more throughput in S3 requests. The smaller
the payload the better the throughput gets.
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.
