ASP.NET 1.1 validation client script - confusing difference on different machines

[Pete Beech]

Hi,
We have an ASP.NET 1.1 webapp, deployed on an integration and a
production server - exactly the same code. One of the

pages has client side validation script, using the validation
Webcontrols. The HTML rendered out from production is

different to that from integration, although they are both running
ASP.NET 1.1 (verified using aspnet_regiis -lk, looking

in IIS mappings, etc).

Apart from minor (but still puzzling) differences in syntax and
formatting, the page from our local machines and

integration has client script like this:

------------------------------
var Page_ValidationActive = false;
if (typeof(clientInformation) != "undefined" &&
clientInformation.appName.indexOf("Explorer") != -1) {
if (typeof(Page_ValidationVer) == "undefined")
alert("Unable to find script library
'/aspnet_client/system_web/1_1_4322/WebUIValidation.js'. Try placing
this

file manually, or reinstall by running 'aspnet_regiis -c'.");
else if (Page_ValidationVer != "125")
alert("This page uses an incorrect version of
WebUIValidation.js. The page expects version 125. The script

library is " + Page_ValidationVer + ".");
else
ValidatorOnLoad();
}

function ValidatorOnSubmit() {
if (Page_ValidationActive) {
ValidatorCommonOnSubmit();
}
}
------------------------------


But the page from production has client script rendered out like this:


------------------------------
var Page_ValidationActive = false;
if (typeof(clientInformation) != "undefined" &&
clientInformation.appName.indexOf("Explorer") != -1) {
if ((typeof(Page_ValidationVer) != "undefined") &&
(Page_ValidationVer == "125"))
ValidatorOnLoad();
}

function ValidatorOnSubmit() {
if (Page_ValidationActive) {
ValidatorCommonOnSubmit();
}
}
------------------------------


Basically, the production one has no alerts when the client script
isn't found or is the wrong version.

Can anyone explain what is causing this change? Is there a patch or a
setting that stops the alerts being rendered?

(I compared machine.config on both machines, and they are identical.)


Hope someone can help,
Cheers,
