long treatment with apache & cgi

Hi ,

I'm putting in place a website with Apache , the web pages are made of
cgi & unix shell (bash more precisely) .

My web pages work but not without a glitch , indeed the intent of
the pages are to do a long treatment (something akin to a batch
treatment = 15 mn (more or less) ) .

The problem is after (let's say 10mn) , the web pages says that the
treatment are done but in 80% of the case , the treatment is still
running ...

I put that line : echo "<meta http-aquiv="refresh" content="10;">"

but it didn't work .


The question is how can I refresh the web pages until the end of the
treatment ?

Any help would be higly appreciated ,
TIA .

Andy
