You can get headers from a request sent via TSFetchURL using standard ATS APIs

 const char *dataStart = TSFetchRespGet(txn, &dataLen);
 const char *dataEnd = dataStart + dataLen;
 TSHttpParser parser = TSHttpParserCreate();
 TSMBuffer buf = TSMBufferCreate();
 TSMLoc hdrLoc = TSHttpHdrCreate(buf);
 TSHttpHdrTypeSet(buf, hdrLoc, TS_HTTP_TYPE_RESPONSE);
 if (TSHttpHdrParseResp(parser, buf, hdrLoc, &dataStart, dataEnd) == TS_PARSE_DONE)
 {
   // you can now access hdrLoc like any other TSMLoc to a header

 }

    You can get headers from a request sent via TSFetchURL using standard ATS APIs, I do it all the time:

 const char *dataStart = TSFetchRespGet(txn, &dataLen);
 const char *dataEnd = dataStart + dataLen;
 TSHttpParser parser = TSHttpParserCreate();
 TSMBuffer buf = TSMBufferCreate();
 TSMLoc hdrLoc = TSHttpHdrCreate(buf);
 TSHttpHdrTypeSet(buf, hdrLoc, TS_HTTP_TYPE_RESPONSE);
 if (TSHttpHdrParseResp(parser, buf, hdrLoc, &dataStart, dataEnd) == TS_PARSE_DONE)
 {
   // you can now access hdrLoc like any other TSMLoc to a header

 }

> TSFetchUrl does not provide any way to get the headers from the result. This patch adds a new API TSFetchHdrGet(), which is analogous to TSFetchRespGet() and returns the headers.
