Thanks Leif, that worked once I realised I needed to add the status with
TSHttpHdrStatusSet(bufp, hdr_loc,
TS_HTTP_STATUS_MOVED_TEMPORARILY);TSUrlHostGetand the location header using
(say)TSMimeHdrFieldCreateNamed(reqp, hdr_loc, TS_MIME_FIELD_LOCATION,
TS_MIME_LEN_LOCATION , &new_field);TSMimeHdrFieldValueStringInsert(reqp,
hdr_loc, new_field, -1, val, val_len);TSMimeHdrFieldAppend(reqp, hdr_loc,
new_field);
To the _response_ header buffer, and so I had to hook my continuation to the
TS_EVENT_HTTP_SEND_RESPONSE_HDR event and wait till then.
The only problem I now have is that my TSUrlHostGet in the
TS_EVENT_HTTP_READ_REQUEST_HDR handler is failing, even though getting it
manually with
TSMimeHdrFieldFind(..
is working, and returns the Host (and port).
thanks very much for all your help
