Chunked encoding + Content-Length = broken

[GoogleCodeExporter]

From the discussion list:

I did the following:
1. checked out and built version 0.9.14.6-414
2. i updated the file src/third_party/serf/instaweb_response_buckets.c. I did 
the following:
#if 0
            /* Are we C-L, chunked, or conn close? */
            v = serf_bucket_headers_get(ctx->headers, "Content-Length");
            if (v) {
                apr_uint64_t length;
                length = apr_strtoi64(v, NULL, 10);
                if (errno == ERANGE) {
                    return APR_FROM_OS_ERROR(ERANGE);
                }
                ctx->body = serf_bucket_limit_create(ctx->body, length,
                                                     bkt->allocator);
            }
            else {
                v = serf_bucket_headers_get(ctx->headers, "Transfer-Encoding");

                /* Need to handle multiple transfer-encoding. */
                if (v && strcasecmp("chunked", v) == 0) {
                    ctx->chunked = 1;
                    ctx->body = serf_bucket_dechunk_create(ctx->body,
                                                           bkt->allocator);
                }

                if (!v && (ctx->sl.code == 204 || ctx->sl.code == 304)) {
                    ctx->state = STATE_DONE;
                }
            }
#endif
            if ((v = serf_bucket_headers_get(ctx->headers, "Transfer-Encoding")) != NULL)
            {
                /* Need to handle multiple transfer-encoding. */
                if (v && strcasecmp("chunked", v) == 0) {
                    ctx->chunked = 1;
                    ctx->body = serf_bucket_dechunk_create(ctx->body,
                                                           bkt->allocator);
                }
            }
            else if ((v = serf_bucket_headers_get(ctx->headers, "Content-Length")) != NULL)
            {
                apr_uint64_t length;
                length = apr_strtoi64(v, NULL, 10);
                if (errno == ERANGE) {
                    return APR_FROM_OS_ERROR(ERANGE);
                }
                ctx->body = serf_bucket_limit_create(ctx->body, length,
                                                     bkt->allocator);
            }
            else
            {
                if ((ctx->sl.code == 204 || ctx->sl.code == 304)) {
                    ctx->state = STATE_DONE;
                }
            }
This solved the problem.
Thanks
