Hi,
Hi,
Yes, though i think this one should added both ppg core
(then the headers will be removed always; this is for efficiency)
and for ppg user group (the user to not accept certain headers)

Thanks Aarno
Is that functionality likely to be added soon?
I don't mind adding it but I'm not sure where it should be added
(I'm fairly new to using kannel)
Something like a ppg group setting?
group = ppg
remove-headers = Content-length,Encoding-Version,Authorization

Hi Paul.
as a quick reply, adding a configuring option to PPG for omitting
certain headers would be
a good idea, if only for efficiency (the transport is over SMS!)
Generally, a gateway would pass
all (expect hop ones) headers, but in this case default behavior is
inefficient.

Hi there
I needed a way to test a PAP interface I wrote to send OMA Email
Notifications as defined in http://www.openmobilealliance.org/
release_program/emn_v10.html
so I added OMA-EMN support to kannel.
OMA Email Notification (EMN) enables the mobile e-mail client to
be notified of a new e-mail via wappush.
Attached is diff of gateway/gw/wap_push_ppg.c and 2 new files.
Code is closely based on wap_push_sl_compiler.c
It works fine but after much testing with SonyEricsson K800i I
discovered that I had to remove all headers from the wap push
except for
X-Wap-Application-Id: x-wap-application: emn.ua
(X-Wap-Application-Id: x-wap-application:emn.ua header is
definitely required by all Nokia phones that support OMA EMN)
It seems that there is no way to configure kannel to leave out
certain headers. Most HTTP headers from the PAP request are
converted to WSP headers e.g. HTTP authorization headers.
In addition to HTTP headers, it seems that the following 2 headers
are always encoded
Content-length
Encoding-Version
Again, OMA-EMN did not work on SE phones if those headers were
present.
I realise that this is probably a bug in the phone that it cannot
handle those headers but it would be great if there was a way to
configure kannel to leave out those headers.
To work-around that problem I unconditionally remove these
headers by adding the following lines to wap_push_ppg.c before the
call to pap_compile()
http_header_remove_all(push_headers, "Content-Length");
http_header_remove_all(push_headers, "Encoding-Version");
That works but it's not a nice solution.
I believe above headers (Content-Length, Encoding-Version) are
optional. It's pointless to send HTTP authorization headers to the
phone.
Adding a configuration setting to tell kannel not to add certain
headers into the WAPPUSH is probably the best solution.
I want to get your opinion on this. Am I missing something here? I
didn't see anywhere in the WSP spec where it says those headers
are required.
I can send on a diff of the code I've written but I thought I'd
wait until I handle the header problem in a better way
This issue similar to issue raised in following thread
http://www.mail-archive.com/[email protected]/msg06941.html
except in this case, it just doesn't just increase the number of
SMS messages required to carry the wappush, it breaks the OMA EMN
functionaly.
