Anders Sandvig's questions

I am looking for a HTTP load balancing solution that will provide the following:

1) Accept HTTP connections on port X and forward them to one of multiple other hosts (and/or ports), either randomly or in a round-robin manner.

2) If the server reply contains a certain HTTP header with a certain value (i.e. 'Magic-Number: 12345'), remember it and forward all following requests containing the same header to this server.

3) At certain intervals, perform a keep-alive test by sending a specified HTTP request to all destination servers. If either server does not reply, stop forwarding to it until it comes online again.

4) (Not crucial, but nice to have) Accept HTTPS connections from clients and translate them to HTTP connections to the servers.

The solution must consist of free and/or open source software and run under Windows 200x Server.

Any suggestions?

Update: Cygwin or Portable Ubuntu (or other Colinux distribution) are also viable options, if they are able to run the appropriate *nix solutions.

I currently use Cygwin and rxvt as my default terminal environment running bash. I would like to be able to scroll in the output window using the mouse wheel. Is this possible?

I realize there are (at least) two different use cases for this:

1) Scrolling in the scrollback buffer while in terminal/input mode (same as sliding the scrollbar on the window itself).

2) Scrolling in programs such as man and less, where using the up/down arrow keys.

Any solution to either cases are welcome.

Update I just realized case 1) is not relevant. This already works. :)

Given this example folder structure:

/folder1/file1.txt
/folder1/file2.djd
/folder2/file3.txt
/folder2/file2.fha

How do I do a recursive text search on all *.txt files with grep from "/"?

("grep -r <pattern> *.txt" fails when run from "/", since there are no .txt files in that folder.)

Is there any way to configure an USB port on Windows to only act as a charger? I want to charge my MP3 player while I'm listening to music, but playback is not available when the device is connected as a removable disk. I would like to disable the "USB" part of the connection and only use it as a power source. Is this possible?
