What exactly Convert To Sub-Request does?

[Guest Arif]

I have a page with 100+ images and all these are captured as individual page elements. What difference it will make to my performance testing, if i convert all the page elements as Sub-Requests?

 

Basically, I want to understand difference between a normal and sub-request.

 

I tried searching the forum for this question, but not able to locate an answer for this.

 

Thanks

Arif

Sub-requests are needed for a proper Referer management. All sub-requests have a main request as Referer.

 

If you convert page element to sub-request it will have own separate statistics in report.
