cgi - Linux bash interruptions -

-

i'm trying put when receives event, , http request apache cgi-bin generate "flag" script picks , execute code?

another "interrupt" push button im getting of problems, becuase want put in loop, if source script sourcing script halt because of loop, if use name pipes halt waiting data...

i've been triying named pipes, sourcing scripts , sorts of things dont manage consistent, wondering thinking on using other ipc options, signals, shared memory , thoose kind of things.

to start have experience this, know resources , if it's possible.

i needed work @ kernel level using inter-process communications socket or known domain sockets
