Hi Sarah,
Your question has probably been answered by now, I found it when trying to find an answer to the same question myself!
I think the answer is Yes, as given by the following paragraph:-

<meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT">

Sets date and time after which the document should be considered expired.
Controls caching in HTTP/1.0. An illegal Expires value like 0 is interpreted as now. Setting Expires to 0 may thus be used to force a modification check (reload) at each visit. Robots may delete expired documents from a search engine or schedule a revisit.

<meta http-equiv="cache-control" content="no-cache">

Sets the action of cache agents. Possible values are

public - may be cached in public shared caches
private - may only be cached in private cache
no-cache - may not be cached
no-store - may be cached but not archived

Note: Browser action for theses headers is undefined.
MSIE is known to cache the document even if this header is present!'

This can be found on

Hope this helps.
