Analytics appear to stop page loading completely

Hi all

 

I have an odd issue. Basically we have F5 with LTM / Analytics in from of two types of CMS systems - EKTRON and SITECORE.

 

LTM is configured to load balance for each system and the pages load correctly - simple round robin - nothing fancy.

 

However if I apply a simple HTTP / Analytic profile, the pages still display OK, but you can see that it appears not to complete downloading. This causes issues for iframes etc on the site...

 

Looking at the page source, we can see that the analytics code is injected at the end of the page after the end tag - is this expected behaviour?

 

Example:

 

Any pointers would be great.

 

analytics
application delivery
cloud
LTM
virtualization
vmware

    Hi Tony,

    We had problems too with the cspm injection on some websites, since that we always disable the cspm injection with following irule:

    when AVR_CSPM_INJECTION {
       AVR::disable_cspm_injection          
}

    Regards

    Micha

      Hi Micha If we add this, doesn't it essentially disable Analytics? So it would be the same as removing the Analytics profile from the Virtual Server? If that is the case, we wouldn't get any statistics would we? Thanks Tony

      It disables just the cspm javascript injection which measures client-side page load time, all other statics will still work
