[APM] URL stops working , location : /my.policy?ORG_URI=1f931c35

hello Team , 

We have a strange issue . User is able to access the url but sometimes the url doesn't work and when he checks in developer tool it has a status code of : 302 Found. After 10-15min it starts to work without any intervention. 

Response Headers :

Connection :  close

Content-Length:0

Location : /my.policy?ORIG_URI=1f931c35

We are using APM for ACL and URL filtering , so where can I find my.policy ? I did not find any logs with this id 1f931c35 in cat apm or cat ltm logs , cat pktfilter logs , cat urlfilter logs .. 

Kindly please advice .
