Server Header Responses

Is this stopping a site getting indexed?

[HocusPocus]

I'm having a bit of an issue getting a site recrawled by SEs. Got plenty of links etc, generally know what I'm doing, but Google has yet to recrawl the revised page(s).

Doing some site checks using
Searchengineworld.com/misc/tools.htm.

The site that I am maintaining has server header response-

Status: HTTP/1.1 200 OK
Server: WebSTAR/4.2(SSL) ID/80108
Connection: Keep-Alive
Keep-Alive: timeout=15, max=4
Date: Sat, 08 Nov 2003 08:55:14 GMT
Content-Type: text/html
Content-Length: 580
Last-Modified: Mon, 15 Feb 2038 15:58:17 GMT

Is this Last-Modified date significant? Does it incorrectly give the date of the last modification of the page? Could it be putting SE spiders off?

Any advice muchly appreciated.

Could it be putting SE spiders off?

This thread should help a lot too..

I followed slashroot's advice in that thread; and also am configuring "custom" Expires headers.

My log files and web host tell me that Google is using If-Modified-Since queries, contrary to a lot of posts saying it claims to but doesn't.

Others have also told me that establishing a Content-Location header response and Accept-Ranges helps;
In the search categories I'm competing in it does seem that the top listings have this in common so although I'm not a qualified expert in this area.. that also appears to be good advice.

HTH ;-)
