WMS and Web Services

[listuser HH]

Hi List,

this is the problem: I have x/y data comming from a normal web service - 
no wfs. I want to show the points in a map. I thought that I get the 
data from the web service and put it via mapscript to a layer. Should be 
possible - but what is to do when I want to serve this dynamic feature 
layer in WMS. At the moment the only thing that I see to solve this is 
to write the data from the web service in file and use this for the WMS.

Is there a better possiblity? Has someone done something like that?

Is there a difference in performance between reading the data from a 
file and adding data directly in mapscript?

Thanks and best regards

Norbert
