Rx and Tx mean "receive" and "transmit" respectively. A request header
will be logged as RxHeader when received from the client, and with
TxHeader when sent to the backend. Likewise, a response header will be
logged as RxHeader when received from the backend and as TxHeader when
sent to the client.

Varnish uses whatever Host: header it received from the client;
otherwise it wouldn't be able to accelerate servers with multiple
virtual hosts. If the Host: header you get from the client is not
correct, you can adjust req.http.host it in vcl_recv or bereq.http.host
in vcl_miss, e.g.:

vcl_recv {
if (req.http.host ~ "^(www\.)?example.com$") {
req.backend = example_backend;
req.http.host = "backend.example.com";
} else {
error 404 "Unknown virtual host";
}
}

i have :

backend other {
set backend.host = "mywebsite";
set backend.port = "80";
}

if (req.http.host ~ "^my.server.with.varnish")
{
set req.backend = other;
} else {
error 404 "The host listed in your request is
not recognized";
}

Is this the same? I'm asking because your configuration won't work ( I have varnish 1.0.2)

You could have told us that a little earlier. Please upgrade to 1.1.

Allready upgraded, but when run varnish get this error:

Expected action, 'if' or '}'
(/opt/varnish/etc/vcl.conf Line 21 Pos 18)
req.backend = apache;
-----------------###########----------

Allright , i forgot write "set" ;)

But have another question: how can I change TxHeader ?

Unless you modify them in VCL, they are whatever the client sends.
