Proxy seem to drop some requests

[svenefftinge]

Bug description

Working on https://github.com/gitpod-io/vscode is currently pretty unreliable, as the started webserver serves a huge amount of files and our proxy regularly seems to swallow some of the requests (no responses).
We have to try reloading multiple times until it works.

Steps to reproduce

1. open gitpod.io/#https://github.com/gitpod-io/vscode
2. wait for the additional window to load (if it stays white you might have seen such a loading issues
3. open dev tools and see network tab.

Expected behavior

No response

Example repository

No response

I notice the same issues with pprof when I run very long profiling sessions. It seems that there is a timeout for requests. Maybe we should at least set them high enough for port location, not sure about workspace location (although it breaks pprof there and preview too).

It seems that there is a timeout for requests

This could indeed be the case. There are two ways where this could fail (in the gitpod.io setup):

• connection proxy -> ws-proxy
• ws-proxy -> actual service
