## Summary
Fixes a bug where sequential HTTP requests with proxy-style absolute
URLs (e.g. `GET http://example.com/path HTTP/1.1`) hang on the 2nd+
request when using keep-alive connections.
## Root Cause
In `packages/bun-uws/src/HttpParser.h`, the parser was treating
proxy-style absolute URLs identically to `CONNECT` method requests —
setting `isConnectRequest = true` and entering tunnel mode. This flag
was never reset between requests on the same keep-alive connection, so
the 2nd+ request was swallowed as raw tunnel data instead of being
parsed as HTTP.
## Fix
3-line change in `HttpParser.h:569`:
- **`isConnect`**: Now only matches actual `CONNECT` method requests
(removed `isHTTPorHTTPSPrefixForProxies` from the condition)
- **`isProxyStyleURL`**: New variable that detects `http://`/`https://`
prefixes and accepts them as valid request targets — without triggering
tunnel mode
## Who was affected
- Any Bun HTTP server (`Bun.serve()` or `node:http createServer`)
receiving proxy-style requests on keep-alive connections
- HTTP proxy servers built with Bun could only handle one request per
connection
- Bun's own HTTP client making sequential requests through an HTTP proxy
backed by a Bun server
## Test
Added `test/js/node/http/node-http-proxy-url.test.ts` with 3 test cases:
1. Sequential GET requests with absolute URL paths
2. Sequential POST requests with absolute URL paths
3. Mixed normal and proxy-style URLs
Tests run under both Node.js and Bun for compatibility verification.
- ❌ Fails with system bun (2/3 tests timeout on 2nd request)
- ✅ Passes with debug build (3/3 tests pass)
