AJAX and NLB

Hi,

how to enable AJAX using a NLB environment?

thanls

what do u mean by NLB environment ??

When i set a DNS name, for example: app.domain.es, then I add two machines to a NLB cluster: pc1 and pc2. Then, I set the IIS host header to app.domain.es. After this settings, AJAX only works sometimes.

This is the error:

PageRequestManagerParserErrorException: ....message could not be parsed...

Thanks and sorry for my english

Hi,molipo

sometimes it works, sometimes it throws Sys.WebForms.PageRequestManagerParserErrorException

This happens when the machineKey used to encrypt/decrypt the viewstate was changed, and more likely this will happen if you keep the page idle for a long time. To avoid this, you need to have a static machineKey.

Check this articlehttp://blog.g9th.com/2007/01/14/unable-to-validate-data-at-systemwebconfigurationmachinekeysectiongetdecodeddata.aspx

Let me know if you need more info.
