.NET HttpRequest from 1.1 to 3.5

We have to ASP.NET applications, one in 1.1 and one in 3.5. In order to log our errors in the same location we are going to create a WebService that the 1.1 app can call. If I inc开发者_Python百科lude an HttpRequest as one of the parameters to the webservice, will there be a versioning problem?

There will be other problem - HttpRequest isn't marked as serializable, nor is MarshalByRefObj.
