Re: ERR_INVALID_REQ on www.megaupload.com

[Felipe W Damasio <felipewd@xxxxxxxxx>]

Hi Again,

I can reproduce this with:

squidclient -v -m POST  -H 'Accept-Encoding: *;q=0.1\nTE:
trailers\nExpect:100-continue\nHost: www.megaupload.com\nConnection:
TE,Keep-Alive\nDate: Wed, 09 Jun 2010 18:49:31 GMT\nContent-Length:
0\nContent-Type: application/x-www-form-urlencoded\n'
'/mgr_ads.php?s=0'

 Looking at the client_side.c code, I found that:


    if (httpHeaderHas(&r->header, HDR_EXPECT)) {
        int ignore = 0;
        if (Config.onoff.ignore_expect_100) {
            String expect = httpHeaderGetList(&r->header, HDR_EXPECT);
            if (strCaseCmp(expect, "100-continue") == 0)
                ignore = 1;
            stringClean(&expect);
        }
        if (!ignore) {
            ErrorState *err = errorCon(ERR_INVALID_REQ,
HTTP_EXPECTATION_FAILED, r);
            http->log_type = LOG_TCP_MISS;
            http->entry = clientCreateStoreEntry(http,
http->request->method, null_request_flags);
            errorAppendEntry(http->entry, err);
            return;
        }
    }

  Is this true? If I don't add "ignore_expect_100" the HTTP request
with it will _always_ fail?

  If this is right, why is that? I don't get it.

  Thanks,

Felipe Damasio
