URI buffer overflow? .asmx request? Confused as usual!

[keta144 () msn com]

I am new to this so if I am placing this question in the wrong place, please accept my appologies and provide the 
correct direction.

I am running a packet sniffer on my computer and I am seeing the following request happening roughly once every three 
minutes. I am wondering if anyone knows what is going on here. 

GET /api/livesuite/broker.asmx?{"header":{"client":{"isvalid":true,"license":"","proof":
"(there were a bunch of letters and numbers here but I removed in case it was a gateway into an account I may have)

The address I am going to is: 63.240.26.65 (belonging to CERFnet).

I am mostly concerned with this being a URI buffer overflow. If anyone can provide any insight, I would be extreemly 
greatful! I understand how the overflow works. I am trying to find evidence to prove that this is a false positive. I 
have looked up the aspx request and mostly what I came up with was Squid reports. Proving that I am not the only one 
doesn't cut it for me although supports the likelyhood that this is normal traffic. This request is in the top 100 of 
the Squid Analysis Report. It is up there with another request I am seeing: api.bigcharts.net/api/livesuite/pickup.asmx?

These requests are puzzeling to me. They are both popping up on my IDS as a URI Buffer Overflow. 

Thank you in advance if you can provide insight.
