I have a question about how neoload handles cookies for Oracle 12c. The cookie is in the following format:
JSESSIONID=aYtSyBquoRodafgYwRTDtLUwADEX3qqwkR4O8g2cfxRTnizyl1bR!-765324210; ORA_ADF_VIEW_LOOPBACK_ID=165066439310056; ORA_ADF_VIEW_REDIRECT=; ORA_ADF_VIEW_WINDOW_MODE=2; ORA_ADF_VIEW_WINDOW_ID=w0; ORA_ADF_VIEW_PAGE_ID=
I think my test is breaking because ORA_ADF_VIEW_LOOPBACK_ID is not properly set (i think it should be set to afrLoop extracted from the previous page)
When you replay a script with NeoLoad, by default NeoLoad automatically handles the cookies.
That means, if the server set a cookie with the "Set-Cookie" command then NeoLoad will use the new value sent by the server.
If your cookie "ORA_ADF_VIEW_LOOPBACK_ID" is a server cookie that means that the value during validation is the one sent by the server.
If it's not the right value then probably your script is not working and that cookie issue is only a consequence.
You should check and compare the previous transactions to make sure that you got the right server responses.
