I am looking for tools for Windows that can act as a reverse-proxy in front of a server to introduce various networking issues like jitter, delays, or packet loss.

My preference is a software solution that will work on Windows. Httpd mod_proxy doesn't appear to support such a configuration, and googling for a tool in this category is proving fruitless.

I find clumsy wonderful :

clumsy makes your network condition on Windows significantly worse, but in a managed and interactive manner.

This this is awesome, no install or drivers. Many other solutions either didn't work and required installing network drivers. – guanome May 2 '14 at 15:46
Clumsy is great, but it only lets you put a max lag time of 3000ms which isn't great. I need a tool that can let me simulate terrible Internet connectivity. – Mr Pablo Jul 21 '15 at 12:40
@MrPablo Just build it yourself then... See – Calvin1602 Jul 21 '15 at 13:08

If you're just testing how your app will repsond to ill-behaved networks, you could do worse that fire up a linux box in front of it with Wansim - I know, you wanted something ON the windows box... but probably doing the delayage there is an unfair test, as you've already bypassed a bunch of the stuff that is under test (eg how the OS & hardware handles packet loss).

I think you're not going to find web proxies to induce this sort of nastiness - far too high level.

Apologies if "testing your app's resilience" is not what you are after... thought i'd make an assumption rather than ask and forget to reply ;)

My actually goal is to test a client's reaction, and verify some changes I am planning to make will improve the situation. – Scott Markwell Aug 18 '11 at 0:36
