The headers parsed after cloning can be detected and cleaned up, the code should be like:
``` for( hdr=req->headers ; hdr ; hdr=hdr->next ) { if ( hdr->parsed && hdr_allocs_parse(hdr) && (hdr->parsed<(void*)t->uas.request || hdr->parsed>=(void*)t->uas.end_request)) { /* header parsed filed doesn't point inside uas.request * chunck -> it was added by resolving acc attributes -> DBG("removing hdr->parsed %d\n", hdr->type); clean_hdr_field(hdr); hdr->parsed = 0; } } ```
Something similar is done in tm after running failure_route.
I think From is cloned if parsed before cloning.
