[kamailio/kamailio] Feature request: Wanted support of Content-ID in append_body_part (#1632)
### Description According [RFC6442](https://tools.ietf.org/html/rfc6442#section-5.1) multipart body may contain payload with `Content-ID` header. Now `append_body_part` support only `Content-Disposition` optional header and not supports `Content-ID`.
Wanted `Content-ID` to implement RFC6442
Is the `Content-ID` along with `Content-Disposition`? Or only one of those headers has to be there?
If both can be, maybe a workaround for now would be to add the Content-ID after the value of Content-Disposition, so the parameter is `c-dispo-body\r\nContent-ID: ...`. Not sure if it works, as I haven't looked at code, but worth trying.
I have test construction ``` append_body_part("<?xml version=\"1.0\" encoding=\"UTF-8\"?><root/>", "application/pidf+xml\r\nContent-ID: target123@atlanta.example.com"); ``` This works for me. Also `Content-Disposition` header not generated as not wanted header.
We can close this ticket. Or need to leave this open?
Kamailio now works but i can see in logs ``` 135(139) CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: freeing already freed pointer (0x7f6b2991e638), called from core: core/data_lump.c: free_duped_lump_list(625), first free core: core/data_lump.c: free_lump_list(504) - aborting ```
The above solution should be good for now. I added a note in the docs about using this mechanism to add additional headers in a body part. If someone wants to add a different function, then it can be done separately. Closing it.
Closed #1632.
