Akamai Configuration

I have done my first akamai CDN implimentation  for  CQ5 publish in my project.   I have listed the prerequisites and the configuration I have implimented.


DNS Setup

DNS Domain has to be configured to set-up with Akamai and for the domain to work its need to be registered and mapped to below name servers. This will allow Domain configurations to work

Following URL is configured for Akamai testing:

http://XXX-performance-testing.utils-XXX.com:4503/


Note: There is another workaround i.e. to register a temp domain via http://dnsdynamic.org
We can register a doming e.g. XXX-performance-testing.dnsdynamic.com and map it to IP: XXX.XXX.XXX.XXX

Hi,

I'm Saranmai. We are working on a project which is a web application. We are facing issue during execution. The error message is displayed as below.
Error -26610: HTTP Status-Code=502 (Proxy Error) for "_https://url”

We are getting this error at the end of the execution irrespective of number of users. We had tried the following options.
1.With proxy and without proxy in runtime settings.
2.Inserted web_cache_cleanup() function
3.Tried with both the versions of Load runner (9.5 and 11.0).
4.Tried with different Load generators
5.Run Vuser as a Process and thread.
6.Checked the IP spoofing.

Can you suggest some solution to resolve this issue.
