Last-Modified Header
Hi,

Still working on a cgi perl script using LWP::UserAgent

with a lot of help received fron moderator Paul.

But now something completely different:

I want to retrive the "Last-Modified Header" but my own (brand new) server does not send this header with the files.



Does anyone know how and/or where to tweak the server (unix apache) so that it starts sending this info with a file-request

I had a look in the Apache config file, but do not find the tweak in there



Regards,

Sanuk

You put the Last-Modified header as a meta-tag in your pages don't you?

Hi Paul,

You are talking about the:

<meta http-equiv="Last-Modified" content="Some_Date">

Tag that is put inbetween <head></head>

But it is not this.

It's the server that generates Last-Modify headers for every File/Page it serves.

Doing a test with LWP::UserAgent

and asking for: $xlastdate = $res->header('Last-Modified');

about 90% of servers returns a Last Modify date of the file.

When checking the source of these pages the:

<meta http-equiv="Last-Modified" content="Some_Date"> Tag is not in the header of the page.

It was the server that generated the response header

My server does not generate this header currently.

Hi,

I am now so far that I know this Last-Modify header is generated by:

Mod_Headers and then just add the header you want to .htaccess

So I have Un-commented Mod_Headers in the config-file, so as to load it.

But now I am blocked again

The manual at Apache for Mod_Headers is not very clear and very confusing at what to add to .htaccess to have the server generate the Last-Modify header.

It mostly talks about cache headers and forgets to give the example for Last-Modify header.
