Hello All,
I have a cgi which generates a html page with javascript menus and an iframe. Each of te menu item targets a cgi in that iframe. I have an user login cgi which performs validation and loads the index cgi which I described above. So by default, I have used some page for <iframe> by specifying "src" attribute. So when user selects a menu this page will get changed. The problem is, the default <iframe src="anypage"> is not loading sometimes...For example after some continuous 10 logins... I thought this problem is regarding browser cache....so I disabled both disk and memory cache of firefox. But still it is not working sometimes. Please let me know if you have a solution for this issue.
Thanks and Regards,
Balakrishnan

The URI referenced by the 'src' attribute of the IFRAME: is it a static page, a dynamically generated disk file, or a page dynamically generated by a CGI? If I understand you correctly, I think it is the third choice. If so, it seems possible to me that while the page is being read in one browser, a concurrent hit on the same URI is causing the page to be regenerated from scratch. In so doing, it must first delete the original, which looks like an empty page on the other browser. I'm more or less spitballing without confirmation of the nature of your system. Make sense?

Thanks. I get your point. As you guessed it is from a CGI. But I tested this with only one browser access. It still seems to occur . Even I replaced my IFRAME src to some local html page and even to google.com. It still shows blank screen some times. Is there any way to control it through Apache settings or even through my code Please let me know if you have some solution for this.
If you need any technical information...on this issue. Please let me know.

If the content of the IFRAME fails to load, even when the content URI is a page generated offsite, then it must not be anything to do with your server. It must be either a browser bug (try different browsers; Iframes are not a strict standard HTML element), or perhaps your page is not being generated with properly formed HTML. Is your CGI using a standard, well debugged library to generate the HTML, or are you generating it with print statements and literal strings? Have you used an HTML validator to test your page? There are a few limitations on the format of the Iframe content; check a good reference on this, particularly with respect to nesting of block-level elements.

Thanks for your suggestions...
I ran Firebug plugin with Firefox to analyze my code but no bug found. yes.I use print statements from CGI to generate html...Let me run any other inspector and find whether my code has any major flaw or not...
