[mapserver-users] wfs client question

I want to query a public wfs server for some data.
Internally, in my DHTML frontend, all lat/lon coordinates are handled in
geographic coordinates EPSG:4326.
However, the WFS server only accepts lat/lon values given with
particular BBOX parameters specified in EPSG:31468, presumably.

Hence, I think that before the making the request for the external WFS
data, I need to convert the geographic EPSG:4326 coordinates to
EPSG:31468 on the fly.

What is the best way to do this?

- - in javascript, on the frontend side?
  -- using ajax requests?
  -- or is there a recommended JS library for coordinate transforms?

- - or on the the wfs client side, i.e. where my mapserver cgi is hosted ?
Manipulating the cgi parameters somehow, before the request is sent out
to the WFS server?


Or am I did I get something wrong about the WFS specification?
This is the first time I interact with a WFS, so please help me out
someone...
