HTTP Status-Code=400 (Session timed out) and 500 (Internal Server Error) of SAP Web

Hi,

I created test script using VUGen.

I used the auto and manual correlation.
"sec_sesstoken" and "URL".
"sec_sesstoken" was auto correlated. 
I correlated "URL" manually .

I checked snapshot and I confirmed that  "sec_sesstoken" and "URL" was got the value.

When I replayed it, I catched this error as below.

"Action.c(156): Warning -26612: HTTP Status-Code=500 (Internal Server Error) for "https://accsapapq.aws.local:44300/sap(cz1TSUQlM2FBTk9OJTNhYWNjc2FwYXBxX0pGUV8wMCUzYUZ3UzhoSTBISkpwdmZWUzFUZktjaERvY1RxejBfRnNvZEF0YUVPdHotQVRU)/bc/gui/sap/its/webgui/7.106/WebRepository/0021008556/SESS_IMAGE?Version=00001&~SEC_SESSTOKEN=F836E6674ADEDDFC" [MsgId: MWAR-26612]"
