Hello! After setup haproxy, png picture not displayed on the site! On the application catalog have the file ‘test\_code\_location.png’. My colleague some time ago added to configs settings for show this picture, but picture still didn’t printed on the page site! may be they are setting was wrong! Instead of a picture on the site I see a picture icon! When I go to this web page without haproxy, the png picture successfully loading !  
How I can try fix it? Thanks

Complex `reqirep` and `http-request replace-uri` rules are intervening and changing the request URI.

Remove them if you don’t want URI changes.

I would strongly suggest to simplify your configuration.
