Yes,  it worked to me too, but I also don't know why.

Let me explain exactly what we had to do so someone perhaps can
explain why we had to do this:

I configured GIT_PROXY_COMMAND pointing to a script with this content:

(echo "CONNECT $1:$2 HTTP/1.0"; echo; cat ) | nc 172.29.0.6 3128 |
(read a; read a; cat )

Later:

git clone git://source.mvista.com/git/linux-davinci-2.6.git

After some time (downloading 117 Mb) it stalled (git-fetch on a pipe
read) and we had to do this to resume and let it finish:

[root@mao2wx23 tmp]# ps -ef | grep git | grep -v grep
opb694    9975  1451  0 01:39 pts/11   00:00:00 /bin/sh
/usr/bin/git-clone git://source.mvista.com/git/linux-davinci-2.6.git
opb694    9985  9975  3 01:39 pts/11   00:01:56 git-fetch-pack --all
-k git //source.mvista.com git/linux-davinci-2.6.git
[root@mao2wx23 tmp]# ps -ef | grep proxy | grep -v grep
opb694    9986  9985  0 01:39 pts/11   00:00:00 /bin/sh
/home/opb694/proxy-cmd.sh source.mvista.com 9418
opb694    9987  9986  0 01:39 pts/11   00:00:00 /bin/sh
/home/opb694/proxy-cmd.sh source.mvista.com 9418
[root@mao2wx23 tmp]# kill 9987

Thanks again for the patience,
