Set TimeOut for SwingWorker

Question

nice day,
1/ how can I get real Html size in kB with intention to set as maxValue to ProgressMonitor
2/ how can I set/synchronize current valueOfDownLoadedHtml in kB to ProgressMonitor throught downloading Html content
3/ how can I set TimeOut for this Tast, (maybe ... could I use Timer)
