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.<br /> <br /> : 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. <br /> <br /> : The optional ''retval'' becomes the return value of the ADP if specified, otherwise an empty string is returned.<br /> <br /> '''EXAMPLES'''<br /> <br /> # The ns_adp_abort after ns_returnredirect ensures no further ADP<br /> # processing happens except the redirect itself.<br /> <br /> ns_returnredirect http://aolserver.com/<br /> ns_adp_abort<br /> <br /> '''SEE ALSO'''<br /> <br /> : [[ns_adp_append]], [[ns_adp_argc]], [[ns_adp_argv]], [[ns_adp_bind_args]], [[ns_adp_break]], [[ns_adp_debug]], [[ns_adp_debuginit]], [[ns_adp_dir]], [[ns_adp_dump]], [[ns_adp_eval]], [[ns_adp_exception]], [[ns_adp_include]], [[ns_adp_mime]], [[ns_adp_mimetype]], [[ns_adp_parse]], [[ns_adp_puts]], [[ns_adp_registeradp]], [[ns_adp_registerproc]], [[ns_adp_registertag]], [[ns_adp_return]], [[ns_adp_safeeval]], [[ns_adp_stats]], [[ns_adp_stream]], [[ns_adp_tell]], [[ns_adp_trunc]]<br /> <br /> ----<br /> <br /> [[Category Documentation]] - [[Category Core Tcl API]]</div>
