JSON Responses are corrupt if served via proxy

[klopfdreh]

Hi,

I'm currenty encountering the problem, that via proxy some JSON responses get corrupted. If I access the proxied server directly the response is valid and everything is working.

Response-Header of proxy (port 8000):

Cache-Control no-cache,must-revalidate
Connection close
Content-Encoding UTF-8
Content-Length 14
Content-Type application/json
Date Tue, 25 Aug 2015 08:05:51 GMT
Server WildFly/8
x-powered-by Undertow/1

Response-Body:

e
{"id":"1251

Response-Header of Wildfly via direct access (port 8080)

Cache-Control no-cache,must-revalidate
Connection keep-alive
Content-Encoding UTF-8
Content-Length 14
Content-Type application/json
Date Tue, 25 Aug 2015 08:16:44 GMT
Server WildFly/8
x-powered-by Undertow/1

Response-Body

{"id":"12522"}

(id may differ, because the actual one is returned from server during the creation process)

Environment:

    "tslint": "^2.2.0-beta",
    "typescript": "~1.4.1"
  }

It looks like the response was shifted somehow and the result was started at a position which is not valid.

I also tried to fix the issue as mentioned in this ticket #73 but without success.

In livereload I already using the new modules serve-static / serve-index to push the files / directories.

Thank you in advance!

Edit forgot to mention the proxy settings:

    {
        context: [ <some context paths containing the rest resources>],
        host: 'localhost',
        port: 8080,
        https: false,
        changeOrigin: false,
        xforward: false
    }

Okay I got it! I only provided the header in this ticket which I thought to be relevant for this issue, but there were others which caused the problem:

They look like:

x-webmethods-cache-control:[no-cache,must-revalidate]

Maybe the brackets are causing the issue?!

@klopfdreh I am willing to bet this is caused by #73 (comment)

Hi @cowwoc - it seems so yes. 👍
