Ajaxtoolkit downloaded for each page

Question

We have a SharePoint Solution that uses the Microsoft Ajaxtoolkit.

I am doing some performance testing and see that the javascript is being downloaded for each page, causing some page to download more than 1 MB.

The type of call that is being made is:

http://serverName/ScriptResource.axd?d=aMbl7-5dNZOmlggsdXNoTVIFa6esvsBgC6BHXX0EL95-pM5lSDjyY8ReL2JvKluJzYr9etKytxzEbXXTRh-bMV2x_m8iGd7S727g4aeKATA1&t=5aa0b262

The file that this is being returned by the above is MicrosoftAjax.debug.js.

Is there a way to avoid the javascript being downloaded for each page?

Answer 1

Use the release library, not the debug one.

See this article on MicrosoftAjax.debug.js:

Once the development stage is finished, you can switch your application to the release version of the script (MicrosoftAjax.js), which is smaller and doesn’t contain the debugging features presented above.
