    Using cache in /base

    Hello,

    I'm using /base and loving it; makes a lot of sense.

    I'd like to cache some output and am wondering what the best route is - my base method is returning a large JSON string which takes some time to assemble from the database. I'd like to cache the output somehow and avoid building up the JSON each time.

    Is there a more elegant method than just writing the JSON out to a file and checking for its mod date?

    Hi Andrew,

    You can use ASP.NET cache (Cache API), more info in here

    http://msdn.microsoft.com/en-us/library/aa478965.aspx

    The syntax is like the session or application (Cache scope is global)

    example:

    Cache["MyJsonResponse"] = listOfData.ToJson();

    For your case i think that sould be something like

    public static string TheJsonMethod(){
    
if(Cache["MyJsonResponse"] == null || booleanToUpdateCache == true){
    
Cache["MyJsonResponse"] = MyData.ToJson();
    
}
    
return Cache["MyJsonResponse"];
    
}

    I forgot...

    In /base, you have to use HttpContext.Current.Cache["NameOfTheCache"]

    ;)
