Save array in Session object

I want to know that can I save arrays in Session object, so I can use in
other pages??

If so, how's it??

Best Regards,

vSample = Split(sSample, ",")

Session("Array") = vSample

For i = 0 to Ubound(Session("Array"))
Response.Write(Session("Array")(i) & " ")
Next

Save array in Session object

Accessing the saved array as:

For i = 0 to Ubound(Session("Array"))
Response.Write(Session("Array")(i) & " ")
Next

returns a complete copy of the array on every reference to Session("Array").

Perhaps not a big issue on small arrays, but on larger arrays it is more efficent to get a local copy of the saved array and work with that...

savedArray = Session("Array")
If IsArray(savedArray) Then
For i = 0 to Ubound(savedArray)
Response.Write(savedArray(i) & " ")
Next
End If

Fair enough. :)

It's also necessary if the saved array is to be modified...

Session("Array")(i) = "new value"

won't update the Session copy of the array, but the following will...

savedArray = Session("Array")
.
.
.
savedArray(i) = "new value"
.
.
.
Session("Array") = savedArray
