Merged PRs

[4.2.0] - 2019-11-14

Summary

  • Now terminates on SIGTERM as can be caused by docker stop or kubectl delete
  • Add --timeout option to configure when to drop a request
  • Add --custom-header option that enables proxied requests to get additional headers attached
  • Support setting of the environment variable CONFIGPROXY_AUTH_TOKEN using a mounted file on the Docker image's container
  • Node version bumped from 10 to 12.13.0 in the Docker image
  • Various dependencies updated, including addressing security advisories from npm audit which do not affect CHP security itself.

Merged PRs

[4.1.0] - 2019-04-01

  • Add --redirect-to option to specify destination port when redirecting http to https with --redirect-from.
  • Add health check endpoint at /_chp_healthz.
  • Docker base image is updated to node/10-alpine from node/6-alpine
  • Dependencies are updated via Renovate

[4.0.0] - 2018-10-12

  • Add support for client SSL certificates for encrypting proxied requests.
  • Update all nodejs dependencies. Most significant is updating winston (logging) from 2 to 3. There is no longer a global logger, instead use this.log.
  • Drop support for node 4. Minimum node version is 6.
  • Support CONFIGPROXY_SSL_KEY_PASSPHRASE env for setting the passphrase of ssl keys (API_SSL for api ssl key).

3.1.1 - 2018-01-15

  • Fix a bug when using the new custom storage backend support where the body of requests could be lost.

[3.1.0] - 2017-11-03

3.1 adds two new features:

  • Add --change-origin passthrough for node-http-proxy's changeOrigin option.
  • Add support via --storage-backend <storage-class> for custom storage classes. See configurable-http-proxy-redis-backend for an example using redis.

[3.0.0] - 2017-09-19

3.0 is a major release because much of the code has been reorganized to adopt some javascript standards:

  • Use ES6 and Promises instead of ES5 and callbacks, which we can do without a compiler because CHP 2.0 required nodejs < 4.
  • auto-format code with prettify (run npm run fmt to auto-format your code after making changes).

There shouldn't be any major changes in 3.0, but marking it as a major upgrade because there could be regressions introduced by the restructuring.

Fixes:

  • Fix routing of /prefix?query where a query parameter was passed exactly on the routing prefix with no trailing slash.

Improvements:

  • Quieter messages for ECONNREFUSED and ECONNRESET, which are generally not indicative of problems, but rather common events of peers disconnecting during a request.
  • The docker image for jupyterhub/configurable-http-proxy is now based on node:6-alpine.

2.0 - 2017-04-05

2.0.4 - 2017-06-21

  • Add logging of all API requests

2.0.3 - 2017-06-12

  • Fix docker image entrypoint, broken in 2.0.2

2.0.2 - 2017-06-07

  • Fix error raised trying to setHeader on an undefined response (e.g. when encountering socket-level error)

2.0.1

Important CHP 2.0.0 drops support for node.js ≤ 4.0.

Added:

  • Add configuration option for proxy timeout --proxy-timeout <n>, Timeout (in millis) when proxy receives no response from target. #86
  • Add configuration options for auto rewrite and protocol rewrite #73:
    • --auto-rewrite, Rewrite the Location header host/port in redirect responses
    • --protocol-rewrite <proto>', Rewrite the Location header protocol in redirect responses to the specified protocol
  • Add low-level code for separate stores of routes to enable future support of other data stores such as Redis #81

Changed:

  • Support only LTS releases and above for NodeJS #82. This means only ≥ 4.0 are supported.

Fixed:

  • Fix behavior to correctly handle children when a parent node is deleted #93
  • Fix closure reference when serving custom error pages #91
  • Improved all-interfaces warning message when ip='*' #94

1.3.1

  • small fixes for node 6 support
  • fix --no-x-forward again (for real, this time)

  • fix handling of ``--no-x-forward`

1.2 - 2016-04-19

1.1 - 2016-01-04

  • add ConfigProxy.proxy_request event, for customizing requests as the pass through the proxy.
  • add more ssl-related options for specifying options on the CLI.
  • fix regression in 0.5 where deleting a top-level route would also delete the default route.

0.5 - 2015-10-05

  • add --error-target for letting another http server render error pages. Server must handle /404 and /503 URLs.
  • add --error-path for custom static HTML error pages. [CODE].html will be used if it exists, otherwise error.html.
  • fix bug preventing root route from being deleted

0.4 - 2015-10-02
