Hi,
I have never tested the limit for the bodyContent of a <put> tag. Internally, it is
transformed to a String, but I don't thing there is a limit to it. The problem can be
a memory one : I think the String is allocated each time you parse the tag ! I am not
sure that it is more memory/time consuming than an include
of another jsp. Need some tests here.
To reduce memory consumption, you can try to declare the body as a static string,
and put it in tag as a scriptlet (<put name="header" value="<%=myBody%>" type="string"
/>). I have never try it, and I am not sure that it is better than using directly the
body.
Personally, when the content is too big, I prefer to put it in a separate file. I
use bodyContent only for small content.
Be care : you can't do <insert> in the body of <put>, because it is a bodyTag ;-(.
