Re: [jetty-users] ServletResponse with ProxyServlet.Transparent is empty

Thanks this looks good. Gave me some new ideas. Has anyone done anything with WebSocket proxying?

Hi,

no problem. Here is the code: http://pastebin.com/k53LgfrW ... this proxy works quite good for me. I can intercept every request/response and modify it.

regards

Care to share your working proxy. I was looking to do something similar. Thanks

Hi,

sry, there was a bug in my code. Everything is fine now :) thank you!

Another little question. I try to build a program that intercepts the http traffic between two nodes. Which means I try to verify every request and response. At the moment I intercept the request in a custom filter in the doFilter method. Is this the best point to intercept the message or would you recommend to use another method? For example override another method in the proxy servlet?

kind regards

I don't know what you mean by "the program halts", I doubt it really halts :)

To modify the content, just allocate another byte[], fill it with what
you want, and pass that to the super.onResponseContent() call.
