I am having a problem using document.lastModified in a client script. From what I can tell, the Last-Modified: HTTP Header is not being sent for all of my pages. It works with my main page (index.aspx), but doesn?t work with any of my other pages. You can check the headers with this url: http://www.delorie.com/web/headers.html When I type in http://www.alleshouse.net/index.aspx. I get this: TTP/1.1 200 OK Cache-Control: public Content-Length: 4713 Content-Type: text/html; charset=utf-8 Expires: Fri, 27 Feb 2004 04:37:56 GMT Last-Modified: Fri, 27 Feb 2004 03:37:56 GMT Server: Microsoft-IIS/6.0 X-AspNet-Version: 1.1.4322 X-Powered-By: ASP.NET MicrosoftOfficeWebServer: 5.0_Pub Date: Fri, 27 Feb 2004 03:47:27 GMT Connection: close However, when I type in any other page, (for instance, http://www.alleshouse.net/contact_information.aspx) I get this: HTTP/1.1 200 OK Connection: close Date: Fri, 27 Feb 2004 03:50:47 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MicrosoftOfficeWebServer: 5.0_Pub X-AspNet-Version: 1.1.4322 Set-Cookie: ASP.NET_SessionId=dbdhhwqpxfzunt3ofdpxqinb; path=/ Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 3693 Any help would be appreciated.
I got totally different result when i tried it Try use the temporary URL to test to be completely sure. quote:Originally posted by Me I am having a problem using document.lastModified in a client script.

That?s really strange! I did as you suggested and tried the temporary url and came up with identical results. I?m not sure how you got different results. Just out of curiosity, what determines the HTTP headers that are sent to the client? If I?m not mistaken, this is all done on the server. I don?t think there is anything I could add in my code to force the headers to be sent. Is this correct? quote:Originally posted by bruce I got totally different result when i tried it Try use the temporary URL to test to be completely sure. quote:Originally posted by Me I am having a problem using document.lastModified in a client script.

OK, I figured out a few things. ASP.NET pages do not send the ?Last-Modified? header. This is kind of strange, but there are a few ways around it. One thing you can do is simply set the header within your code. ie (C#):
To my knowledge, http header is set by the server. I am not sure if you can manipulate it through code. I would try search in google. quote:Originally posted by Me That?s really strange!
