Hi @adityaumrani , for *POST/PUT* method, `Content-Length` should present
or use Chunked Transfer Encoding (present `Transfer-Encoding: chunked`). And,
ATS has a dedicated function - `HttpTransact::check_request_validity` for this
check.
```cpp
// Require Content-Length/Transfer-Encoding for POST/PUSH/PUT
if ((scheme == URL_WKSIDX_HTTP || scheme == URL_WKSIDX_HTTPS) &&
(method == HTTP_WKSIDX_POST || method == HTTP_WKSIDX_PUSH || method
== HTTP_WKSIDX_PUT) &&
s->client_info.transfer_encoding != CHUNKED_ENCODING) {
if ((s->txn_conf->post_check_content_length_enabled) &&
!incoming_hdr->presence(MIME_PRESENCE_CONTENT_LENGTH)) {
return NO_POST_CONTENT_LENGTH;
}
if (HTTP_UNDEFINED_CL == s->hdr_info.request_content_length) {
return INVALID_POST_CONTENT_LENGTH;
}
}
}
```

I think we can just skip doing this here and let the function check it some
later.
