After reading [http://blog.portswigger.net/2017/07/cracking-lens-targeting-https-hidden.html](http://blog.portswigger.net/2017/07/cracking-lens-targeting-https-hidden.html).  
I wanted to do  
$ pathoc [google.com](http://google.com) [get:@tester.com](mailto:get:@tester.com)

But I get an error as below. It seems we cannot start a path with ‘@’ symbol. Or Am I doing something wrong. Pathoc seems really powerful feature to test HTTP protocol/servers but this seems to not work.

I realized it is due to ‘@100’ type of feature. Maybe we should add a flag to disable the interpretation of ‘@’ or such symbols. While at it, we can perhaps support any text in place of GET method.

EDIT: created a feature request: [https://github.com/mitmproxy/mitmproxy/issues/2497](https://github.com/mitmproxy/mitmproxy/issues/2497)
