In your case you have two operations at the same offset in the message -
nathelper adding a remove and add lump and you (via replace) doing the
same. There is nothing you can do about this.....
So you are saying that if it happens that two separate and independent
modules for a pure chance modify the same header field, the resulting
message is corrupt???
I think this is a GREAT limitation (I'd call it a bug) of the lumps
handling code...

the issue.
I don't understand the issue. I cannot see the problem if the header
field was actually removed and then re-added.
The problem is that the header field is present in BOTH forms (long
and compact): "l:Content-Length:".

If you want short header names, the best is to change the sources and
update the define at config.h line 70 to compact form of content
length header. In the future, maybe only the body of the header
should be updated, and this issue will go.
Cheers,

The message size is updated but the header field name appear in both
the short and long form. Here it is an example:
l:Content-Length: 403
The result is the same if I reverse the order of the two operations
too.
BTW, I use that replace call (and others) when the message is large
to prevent it to fragment.
Bye.
