A simple proxy that firewalls the requests that are passed through. Currently supports filtering by query parameters.
Example config:
{
"url": "http:\/\/localhost:32769",
"queryRestrictions": [
{
"key": "url",
"valueRegex": "^https:\/\/www\\.google\\.com"
}
]
}
Will allow only URLs that have query params where the value of url beings with https://www.google.com.
Required ENV vars:
PORT and CONFIG, where CONFIG is the base64 encoding of the JSON above, like ew0KICAidXJsIjogImh0dHA6XC9cL2xvY2FsaG9zdDozMjc2OSIsDQogICJxdWVyeVJlc3RyaWN0aW9ucyI6IFsNCiAgICB7DQogICAgICAia2V5IjogInVybCIsDQogICAgICAidmFsdWVSZWdleCI6ICJeaHR0cHM6XC9cL3d3d1xcLmdvb2dsZVxcLmNvbSINCiAgICB9DQogIF0NCn0=
