This was asked before to no avail. Other than the creation date that is printed on a webpage by the developer, is there a way to determine the chronological date of a webpage? Sincerely, Barry Karas |

It was asked before and *answered* before. At length. Apparently you just didn't like the answers. This doesn't change them, however. The only way to determine a chronological date of a webpage that is not under your direct control (eg., your very own webpage that you created yourself) is if the webpage creator puts something to that effect on the page such as a change log or the like. So I suppose you could say you previously asked "to no avail" but "and I didn't get the answer I wanted to hear so I'm asking the same thing again" more accurately depicts what you are doing.

That is something queried and answered with the HTTP. So you need a program that uses this and lets you see the answers. For your ordinary web-browsers; 'Firefox' lets you see this via 'about:cache' 'Internet Explorer' lists this as one of the columns in the 'Temporary Internet Files' pseudo-directory. 'Opera', i'm not familiar with how to do it there. That only shows you when the page was accessed. The OP wants to know when the page was *created* or *updated* by the website owner.

If you are talking about the {Internet Explorers/Windows Explorers} TIF pseudo-folder, mine shows different columns for 'Last Modified' and 'Last Accessed' as well as another one for 'Last Checked'. As i remember it 'Last Modified' values can show realistic dates like 2005, 2002 for web-pages that hasn't been updated since these dates. -- Nah-ah. I'm staying out of this. ...

No, for the last time: the OP had a different thread where he asked the same question. What he wants to know is a way to tell when the *content* of a webpage has been updated. He wants to know if a website was last worked on by the website owner in 1998 or last week. So no, we aren't talking about anything available on the local computer because what the OP wants is not possible unless the person who wrote the webpage puts that information on it. EOT for me.

Yes, it is possible .. by looking at the HTTP communication: RFC2616 "Hypertext Transfer Protocol -- HTTP/1.1" http://www.ietf.org/rfc/rfc2616.txt Quote:
modified date but a web-server *should* include that value in the response, and from what i have seen usually does. However, i just checked the 'about:cache' in Firefox after going to a web-site i made and put out on the web and that i haven't updated in a few years. Unfortunately the 'Last modified' line there shows todays date, in other words it is more the 'current access date' then the last modified one, so i was wrong to state that that is the place to look it up. EOT for me. Malke Fine. you are just plain wrong that it isn't something the OP can get to know. The OP just need to use a tool that shows the web-servers HTTP response for a web-page or other whatever resource he 'GET's. -- Nah-ah. I'm staying out of this. ... Now, here's my opinion.

Ahh, yes this is how i see it in Firefox: Request a web-page. From the menu choose 'Tools' : 'Page Info' On the 'General' tab look at the 'Modified' date given. For the homepage on the above mentioned site i see: Modified: 28 June 2005 12:52:11 I really should start thinking about updating it. :-) I must say i was taken aback by what the 'about:cache' page shows .... ahh, but now i remember, i have to click just one link further and i'll get to see the HTTP-server response: Client: HTTP request-method: GET request-Host: (www.server.com) - modified response-head: HTTP/1.1 200 OK Date: Fri, 09 May 2008 03:01:30 GMT Server: Apache/1.3.32 Vary: Host Last-Modified: Tue, 28 Jun 2005 11:52:11 GMT Etag: ("nnnnnnn-nnnn-nnnnnnnn") - modified Accept-Ranges: bytes Content-Length: 4329 Content-Type: text/html charset: ISO-8859-1 Easy as pie. Down to the second man! Well one hour on or off. -- Nah-ah. I'm staying out of this. ... Now, here's my opinion. Please followup in the newsgroup. E-mail address is invalid due to spam-control. |

. .. 8/May/2008 6:50 This was asked before to no avail. Other than the creation date that is printed on a webpage by the developer, is there a way to determine the chronological date of a webpage? Firstly, the date shown on a webpage is either fake or a waste of time. Some sites generate the date on demand, so its always today or very recent. If the date is genuine then all it shows is if the web page hasn't been updated for a while. As a web developer it isn't something I ever put on a page. Secondly, this isn't really an xp question, so it might have been better asked in a webmaster newsgroup such as alt.www.webmaster. As to whether you can determine the chronological date of a webpage this depends on the type of page and I suppose in part on the web-server. If the page is dynamically generated (so say a .asp, .aspx, .php, .pl etc) then other than downloading the page and comparing it with a previous version I don't think there is any way. If the page is static html (so .htm or .html) then you can query the server for the age of the file. For example if you use CryPing (free from http://www.cryer.co.uk/downloads/cryping/) then you can view the heads returned for a page, so: C:\cryping -v -n 1 -http www.cryer.co.uk CryPing - from www.cryer.co.uk v1.3 (build April 2008) Pinging www.cryer.co.uk for http status: Reply from www.cryer.co.uk: 200 OK time=67ms HTTP/1.1 200 OK Date: Fri, 09 May 2008 10:46:07 GMT Server: Apache/1.3.39 (Debian) Vary: Host Last-Modified: Fri, 18 Apr 2008 18:40:40 GMT ETag: "6ce6870-2350-4808eb28" Accept-Ranges: bytes Content-Length: 9040 Connection: close Content-Type: text/html; charset=iso-8859-1 and the "Last-Modified" shows you when the page was last changed, in this case in April of this year. However I don't know whether all servers return "Last-Modified", and as I indicated above it probably won't be included for dynamic pages or if it is then it won't be meaningful. Even when there is a "Last-Modified" date from the web-server, the date is the date of the file at the server and this is likely to be slightly more recent than when the webmaster modified the page. The reason is that pages are typically transferred to a webserver by FTP and FTP does not preserve date stamps, it creates files with the datestamp that reflects when the file was copied up. So if the webmaster is using an unintelligent FTP program and simply copies everything up to the server then the date simply reflects when the webmaster last pushed the upload button and not when the file was last modified. Hope this helps. -- Brian Cryer www.cryer.co.uk/brian |
