This repository contains a trivial helper for making secure HTTP-requests with golang.

Imagine you have a service to which users to submit tasks containing references to remote objects (HTTP-URLs).

• For example you might allow users to enter the location of a HTML document.
• Your service fetches that remote resource, then converts it to PDF, or similar.
• The results are then shown to the user.

Now imagine what happens if the user supplies URLs such as these, as input to your service:

• http://localhost/server-status
• http://169.254.169.254/latest/meta-data/

This package allows you to prevent these inputs from being processed, easily.

Sample usage can be found in remotehttp_example_test.go.

This wrapper-library only considers the case of http and https schemas; if you're accepting URIs of your own you should absolutely sanity-check you've not been given something with a file://, or ftp:// prefix (and more!)

Other things you'll want to consider:

• Resource limits such as timeout-handling.
• Resource limits such as whether to follow redirections, and if so how many.
