Retrieving the date of a web page

Hi all,

I want to retrieve the date(s) of a URL, when it was created, etc.

The idea is to automatically know if any changes have been made. I'm now using the Inet Control to download the page every day and compare it to a previously saved version, but I really think it's a bit of a waste of time.

Any ideas would be appreciated. Thanks in advance.

Maikell.

Re: Retrieving the date of a web page
To get the last modified date of a file you can use this.
VB Code:
```
DEbug.Print Inet1.GetHeader ("Last-modified")
```

Re: Retrieving the date of a web page

mm, this looks as if it should work. However, I keep getting a #35756 error ("can't finish operation/petition"... I don't work in english...)

Can it be that the page doesn't have that precise tag in the header (or it's called some other way)? Is there a way to retrieve all header's tags? I'm trying with www.vbforums.com, for example.

Re: Retrieving the date of a web page

This works for me :)

VB Code:

Inet1.URL = "http://www.yoursite.com/yourfile.zip"
 
Debug.Print Inet1.GetHeader("Last-modified")

May have something to do with the regional settings... I work in spanish...

Do you know how I can get a list of the headers' tags? I guess "Last-modified" may translante as "Ultima-modificacion" or something like that...

OK, it seems it was just that you need to

Inet1.Execute , "GET"

before you can get the header info. I still wonder where to find a list of all the info the header can give me, but it's ok.

Thank you so much for your help!

From MSDN....HTH :)

The GetHeader method is used to retrieve header text from an HTTP file.

Syntax

object.GetHeader (hdrName)

The GetHeader method syntax has these parts:

Part Description
object Anobject expression that evaluates to an object in the Applies To list.
hdrName Optional. A string that specifies the header to be retrieved.

Return Type

String

Remarks

If no header is named, all of the headers will be returned.

The table below shows some of the typical headers available.

Header Description
