NAME
- ns_adp_abort - Stop processing of the current ADP and discard queued output
SYNOPSIS
- ns_adp_abort ?retval?
DESCRIPTION
- This command stops processing of the current ADP by throwing a Tcl error along with an "ADP exception" of ADP_ABORT. This has the side-effect of truncating the current ADP's output buffer so that no queued output for the current ADP is sent to the client.
- However, if a streaming script was processed before ns_adp_abort was called, the data will already have been output. Also, if any commands that cause output, such as ns_return or ns_write for example, were called before ns_adp_abort, then their output will already have been output also.
- The optional retval becomes the return value of the ADP if specified, otherwise an empty string is returned.
EXAMPLES
# The ns_adp_abort after ns_returnredirect ensures no further ADP
# processing happens except the redirect itself.

ns_adp_abort
NOTES
- Because it's possible to catch the ns_adp_abort exception, it is possible for code to execute after an ns_adp_abort in the current adp block. However, all subsequent adp blocks are guaranteed to not get evaluated. For example:
<%
catch { ... some code that executes ns_adp_abort }
if {[ns_adp_exception] eq "abort"} {
... some cleanup code
}
%>
<% ... this next block will NOT be evaluated even though ns_adp_abort is caught in the prior block %>
