Due to some limitations about the web services I am proxying, I have to inject some JS code so that it allows the iframe to access the parent window and perform some actions.
I have built a proxy system with node-http-proxy which works pretty nicely. However I have spent unmeasurable hours trying to modify the content (on my own, using harmon as well, etc) that is being sent to the user without any success. I have found some articles and even some questions here but all of them are outdated and are not useful anymore.
I was wondering if someone can give me an actual example about how to do this, because I am unable to do it and maybe it is just that it is impossible to do at this point?
