Hi,
A feature I would like to have / implement in Kannel is HTTP header
filtering.
Most urgent I would like this feature for the PPG.
Currently, if you submit e.g. by "curl" a PPG request, the generated
short message(s) even contains the "curl" user-agent, together with some
other useless headers of the "outer" HTTP request. This is certainly not
worth extending the push from 1 to 2 short messages.
However, I think the feature of filtering headers also for normal WAP
requests and responses makes sense.
E.g., the "Server" header is included in nearly every HTTP response, but
rarely of use for a mobile client.
I would like to suggest a header white-list and a header black-list that
can be configured in Kannel, e.g.
For wapbox:
request-headers-white-list / request-headers-black-list
response-headers-white-list / response-headers-black-list
For PPG:
headers-white-list
headers-black-list
A useful sample for the PPG would be:
group = ppg
headers-white-list = "X-Wap-Application-Id Content-Type"
I understand that filtering especially HTTP request headers for Wap
requires in-depth understanding of HTTP.
But I would prefer a "symetric" solution.
Could I get comments on this?
Best regards,
Georg
