I would like to use substitution feature of donut caching.
public static string GetTime(HttpContext context)
{
return DateTime.Now.ToString("T");
}
...
The cached time is: <%= DateTime.Now.ToString("T") %>
<hr />
The substitution time is:
<% Response.WriteSubstitution(GetTime); %>
...But I would like to pass additional parameter to callback function beside HttpContext.
so the question is:
How to pass additional argument to GetTime callback?
for instance, something like this:
public static string GetTime(HttpContext context, int newArgument)
{
// i'd like to get sth from DB by newArgument
// return data depending on the db values
// ... this example is too simple for my usage
if (newArgument == 1)
return "";
else
return DateTime.Now.ToString("T");
}
