picoded/http-simple-proxy: passing "Host:" header

[stephenfrank]

Hi,

I've been using this container image in a few instances since it fills my needs for a "http-simple-proxy" 😋

I found that I really needed the original "Host:" header forwarded I've done so by adding an extra line of configuration to my version of the container:

        echo 'echo "      proxy_pass_request_headers    on;"                                     >> default.conf' >> /entrypoint/primer.sh && \
        echo 'echo "      proxy_set_header     X-Forwarded-For \$proxy_add_x_forwarded_for;"     >> default.conf' >> /entrypoint/primer.sh && \
        echo 'echo "      proxy_set_header     Host \$host;"                                     >> default.conf' >> /entrypoint/primer.sh && \

I thought it would be good to share and you could see if there is a way to add this as a configurable option or maybe just in the base image.
