Not working: TSHttpHdrDestroy ?

Hello list, I'm on a forward proxy setup working with a plugin. I need to
delete a Header that comes from the user browser so it doesn't make it to
internet.
For this I'm trying to use TSHttpHdrDestroy, but it's doing nothing.
I get the right pointer to the header, but I'ts not destroyed.
Any light on this?
This is my current code:

Thanks you!


void
remove_internalid_header(TSHttpTxn txnp, TSCont contp)
{
  TSMBuffer bufp;
  TSMLoc hdr_loc;
  TSMLoc field_loc;

  if (TSHttpTxnClientReqGet(txnp, &bufp, &hdr_loc) != TS_SUCCESS) {
    TSError("couldn't retrieve client request header\n");
    return;
  }

 field_loc = TSMimeHdrFieldFind(bufp, hdr_loc, "Inid", 4);

 TSDebug("myfirstfilter", "Inid field_loc=%p\n", field_loc); //this shows
the right pointer

  if (!field_loc) {
    TSError("no InId field\n");
  }

  TSHttpHdrDestroy(bufp, hdr_loc);

  if ( TSHandleMLocRelease(bufp, TS_NULL_MLOC, hdr_loc) != TS_SUCCESS) {
    TSError("unable to destroy InId field\n");
  }

  return ;
}

In this case is better to have everything contained on the same plugin.

Also, depending on what else your plugin is doing, your use case above is exactly why we have that header_rewrite plugin.

That'll be TSMimeHdrFieldFind / TSMimeHdrFieldDestroy you're
looking for.  It's just the one MIME header!
