I learned this the hard way. Not only was I doing next and previous
buttons, but I had listed pages as well. I removed all the "_" from
"_function" and turned debug on and watched as every click added more
uneeded args to the post. After clicking 20 or 30 pages, the "next"
would would pretty much crawl to a stop with hundreds of the args
being passed.
That makes sense. Thanks for the info!

Subject: Re: Witango-Talk: Question about argument names
There is no speed improvement by using _function but if you
look at the
code that builds the next previous buttons in the search builder you
will see where the _ before an argument is used and why
Everyware built
it this way.
This routine removes the args that start with an _ as it is
assumed to
be a "witango" control arg (_function, _start) and should not be
created as a hidden field.
<@ROWS ARRAY=request$arg_names>
<@ASSIGN request$arg_name "<@COL 1>">
<@! Ignore args beginning with _ as they will
be passed manually. >
> <@IF "'<@LEFT @@request$arg_name 1>' != '_'">
<@! Assign the current argument values
to a variable. Use TYPE=ARRAY
to get all the values for multi-select lists.>
<@ASSIGN request$arg_values "<@ARG
@@request$arg_name TYPE=ARRAY>">
<@! Loop through all the values for the
current arg. Build a hidden
form field for each. Append field HTML to existing HTML.>
<@ROWS ARRAY="request$arg_values">
<@ASSIGN
request$search_vals_HTML '@@request$search_vals_HTML<input
type="hidden" name="<@VAR request$arg_name>" value="<@COL 1>"
/><@CRLF>'>
</@ROWS>
</@IF> <@! End ignoring args beginning with _ >
</@ROWS>
The reason for ignoring them is that they are manually added to the
form action and do not need to be added as a hidden post arg.
<form method="post"
action="<@APPFILE>?
_function=list&_start=@@request$new_start&<@UserReferenceArgument>">
If they were not stripped out, every iteration of the next/previous
functionality would add more and more of the same arg and so
you would
end up with multiple values for the args controlling the loop. You
would also have a http header that was continually growing in
size as
more and more hidden post args are created. If you want to see the
affect, do a global change on _function to function in a search
builder. Turn debug on and look at the post args that are passed
through. In this situation, after quite a few next
iteration, you will
see a slow down in both the web server and witango server as
they have
to process an every increasing number of post args in the http header.
