Post by thread:[OT]: Calling HTML/CGI wizards....Auto page refres

Hi, I wanted to implement a quick and dirty way of refreshing a page generated from a CGI script. It's quite easy to do it the dirty way, with the <META HTTP-EQUIV="Refresh" tag arrangement but it expects a URL to be specified.... As I have "written out" the META tag via CGI, I don't have a specific URL to refresh "back to." The page can be manually refeshed via a submit button; is there a way of embedded the "submit" into the meta tag so that the refresh pretends that the submit button is being pressed? Is it as easy as just specifying the Perl/CGI script that would be normally called on the submit? OR, better still, can anyone suggest a better way of doing this? I know I could write out some javascript to a tiny frame that refreshes a main frame or something but I'd like to keep it simple (as it has to work on Linux Lynx!) Any help would be greatly appreciated, Dan PS: This is PIC related! I am trying to refresh data from an Internet-enabled embedded PIC -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

Never tried it, but I think 'Connection: open' in the header might do the trick... at the expense of a TCP connection on your end.

How about entering the cgi script in the refresh? You can sepcify parameters on the command line (which would be the same as the parameters received for the first call in your case). For instance, lets assume you received a name parameter and I entered Steve... you could write out the refresh tag with the folloring url: http://www.yourdomain.com/cgi-bin/somescript?name=steve There are other conversions necessary to escape spaces and other special characters... but that's a start... look up CGI on the net to get more info on the character escapes, sending multiple parameters, etc. Steve ------------------------------------------------------------------------ Steven J.

Hi, Sorry to waste bandwidth but thanks to everyone replying on these subjects recently. I bit the bullet and have some javascript refreshing frames, now, which seems the best solution.

Maybe I do not understand the question, but what is stopping you from using the CGI request (unparsed) of the CGI script to build the tag that Refresh references ? Maybe with a little change (added variable) to indicate it is not the first call ? Peter -- http://www.piclist.com#nomail Going offline?
