asp.net web service and page method
<p>For the moment, I have a page method that I call with javascript/jqeury and the server returns a json object. I'm realizing that I'd actually like to have this page method on every page. Of course, I could copy paste the page method on every page but I'm looking into better options.</p>

<p>1) Putting the page method in the master page. Is this easy to do? </p>

<p>2) Creating a web service. My question is this: for now, the page knows which client is requesting the method through the sessionID; does a web service also know who's calling it? In term of performance, are they comparable?</p>

<p>Let me know you have any suggestions and what I should watch out for.</p>

<p>Thanks.</p>
