e.g., if I want to do something if there is a Refer-To header in the
message,
am I better off doing
avp_printf("$someAvp", "$rt");
avp_check("$rt", "re/.../i");
or
search("/.../");
Just want ot know whether to get started rewriting all the "search()"
strings i have in my ser.cfg....
cheers

Hi Kanakatti,
IMHO , the first approach should be faster and saver.
why faster? instead of applying re over the entire message (as search
does), you will limit to the hdr body. Parsing to extract the hdr is
also more faster (and usualy means just walking over the hdr list, since
the msg may be already parsed).
why saver? re to match exactly the hdr and the check the body, excepting
that are complex and slow, may fail and do wrong matching - the internal
hdr parser cannot fail and always identify precisely the hdr.
regards,
bogdan

If you want just to check if there is a Refer-To header, you can use the
function is_present_hf() from textops module. This is the fastest way to
check if a header exists.

True. and agreed.
I was actually trying to be more general, i.e., if I wanted to do some
processing on the contents of a specific header, would it be more
efficient to extract that header using avp_printf(), and then search
within it, as compared to just searching on the whole message
The answer, as it turns out, is that yes it is probably faster (limited
to walking through and extracting just the header), and safer (less
chance of matching against something else altogether)
thanx

Hi Kanakatti,
for extracting an hdr into an AVP, you can use avp_write() instead of
avp_printf() - it's faster since it's not so complex ;)

this reminds me about the thing that is_present_hf() implementation is
not very efficient, because it compares header names as strings. this
could be turned into type comparison with aid of a fixup function (for
all hfs known to ser).

i checked and, indeed, this is true. it is ser that still uses string
comparisons.
