ASIHTTPRequest wsdl2objc Merge

[indio]

Hi all,
i successfully developed my App which make use of webservices. I generate the WS code using wsdl2objc and, with some modifications, all seems to work fine.
Now the problem is that devices are often behind an HTTP proxy which need authentication. Even if i configure proxy parameters in iPhone4 wifi configuration, my App is still unable to go to Internet.
I'm planning to use ASIHTTPRequest which seems to solve the problem regarding proxy HTTP access but i have to embed ASIHTTPRequest calls in the wsdl2objc generated code.
Did someone have allready tried this? Can some one poit me in the right direction of give me some hints?
Thanks
Fabio
