login Page Query

Hello All,

On the Portal Landscape 'A', the Logon page with some custom code is working fine, When we are typing the URL http:
<server>:<port>\irj\portal. The page and the functionality is displayed as on the expected lines

But When we download the respective com.<customernamespace>.portal.logon.par file , I am unable to see the custom code changes. Can anyone suggest what might be the reason for the same please.

Or is there a possiblity that the code changes have being overwritten ?, by standard code during some portal landscape system upgradation and maintainance.

Is there any alternative way for How can i retrieve/fetch the code running on the server.

Thanks
