# http-shadow
Compares HTTP responses from two different backends
### How to run
1. Set up virtualenv with python 3
2. Install dependencies by running `python setup.py develop`
3. Run the following (preferrably in `screen`):
```
get_urls | check_urls
```
This will pipe URLs found in Apache access log to the process that will perform two requests: to Apache and to Kubernetes. Response code and headers will be compared and results logged via syslog with `http-shadow` ident.
4. To compare production vs k8s-powered sandbox use:
```
get_urls | check_urls
```
