Selecting backend and normalizing host header :

sub vcl_recv {
        if (req.http.host == "source-qa.example.co.il<http://source-qa.example.co.il/>" || "source-qa-pp.example.co.il<http://source-qa-pp.example.co.il/>" || "qa.example.co.il<http://qa.example.co.il/>") {
                set req.http.host = "qa.example.co.il<http://qa.example.co.il/>";
                set req.backend = example_qa;
}
}

sub vcl_recv {
                if (req.http.host == "source-qa-test.co.il<http://source-qa-test.co.il/>" || "qa-test.co.il<http://qa-test.co.il/>" ) {
                                set req.http.host = "qa-test.ynet.co.il<http://qa-test.ynet.co.il/>";
                                set req.backend = test_other_sites_qa;
}
}

Now the problem is that  when I send a request with one of the host headers  "source-qa.example.co.il<http://source-qa.example.co.il/>" || "source-qa-pp.example.co.il<http://source-qa-pp.example.co.il/>" || "qa.example.co.il<http://qa.example.co.il/>"

The request is always sent to  test_other_sites_qa which is the second backend and not the correct one .

Hi,

It seems the second vcl_recv subroutine is matching for every request. You should write:

            if (req.http.host == "source-qa.example.co.il<http://source-qa.example.co.il/>" || req.http.host == "source-qa-pp.example.co.il<http://source-qa-pp.example.co.il/>" || req.http.host == "qa.example.co.il<http://qa.example.co.il/>") {
                                ...

            if (req.http.host == "source-qa-test.co.il<http://source-qa-test.co.il/>" || req.http.host = "qa-test.co.il<http://qa-test.co.il/>” ) {
                                ...

Cheers,
