(I have two different configurations that both have this problem: apache 1.3.26 with embperl 1.3.6, and apache 1.3.9 with embperl 1.2b11.)
The problem is that sometimes when a user clicks a button to submit form data, the values in the form are apparently not sent back to the server. The result is that the user sees either an error message or the application's entry page (because the application doesn't find form data that indicates what it should do).
From what I can tell, the browser is succesfully contacting the URL in the "action" attribute of the <FORM> element, but none of the form data seems to be received. The embperl log doesn't show any error message, just a call to the application page with no "[xxxxx]FORM: name=value" entries, as if the user had come in at the starting page.
I have seen this problem in two different applications, one which uses individual HTML pages with unique names (e.g., page1.epl, page2.epl, etc.), and one which uses a frameset which contains a frame that has an Execute statement that executes a different chunk of embperl depending on the "nav_choice" (navigation choice) value submitted.
I think the problem occurs only with <FORM> elements; I can't recall whether it has been reported when a user clicks a link containing a query string (the application uses both).
The last few reports of this problem have all come from people using Netscape Navigator 4.7x, and I don't know if that's a coincidence or not. I think the problem has occurred with other browsers, but I don't have figures to show how often.
Does this sound like a familiar problem to anybody? If you build a web-based application, do you have to accept that a certain percentage of button clicks by users are simply going to fail?
Where would you look further to find the cause of this? Would you suspect that the browser is not correctly sending the form data (out of my control, as long as my HTML is valid), or the data is sent but somehow not reaching our web server (also out of my control), or the data reaches our web server but somehow embperl loses it?
ANY suggestions or advice would be most gratefully received.
