- Bundle the golang.org/x/net/proxy package to x_net_proxy.go. The
package contains a SOCKS5 proxy. The package is bundled to avoid adding
a dependency from the weboscket package to golang.org/x/net.
- Restructure the existing HTTP proxy code so the code can be used as a
dialer with the proxy package.
- Modify Dialer.Dial to use proxy.FromURL.
- Improve tests (avoid modifying package-level data, use timeouts in
tests, use correct proxy URLs in tests).
Fixes#297.
