Npm is pushing slashes and lowercasing letters while retrieving proxy !

[as-ajitsingh]

I'm opening this issue because:

- [ ] npm is producing an incorrect install.
- [x] npm is producing incorrect or undesirable behavior.

• npm is doing something I don't understand.
• npm is crashing.
• Other (see below for feature requests):

What's going wrong?

I am using npm behind my corporate proxy but even after adding proxy and https-proxy to .npmrc file. I am not able to install dependencies still it is giving the proxy error.
On checking my proxy through the console ( npm config list ), I noticed that it is automatically putting forward slash before URL encoded characters and lower casing capital letter in password.

Is it something expected/ Am I doing something wrong ?
