Web Cache's versus Server Side Includes

Tama · Jul 2, 2001

Hello - I run a website (

http://www.vorb.org.nz)

which uses quite a lot of server side includes. For example my home page (

http://www.vorb.org.nz/index.htm)

has the main body as a server side include (

http://www.vorb.org.nz/news.htm)

so I can 'live-edit' news & updates using Frontpage 2000 & Frontpage components.

I've been running into a frustrating problem - where I edit

http://www.vorb.org.nz/news.htm

and then try and view my work.

What seems to happen is the Web cache (at my work or ISP) checks

http://www.vorb.org.nz/index.htm

- decides it hasn't changed (it will have the same date stamp and same file size) and load the cached version of index.htm which still has the old version of news.htm imbedded in it.

Even using Ctrl-F5 on IE doesn't seem to work as far as retrieving a "fresh copy" of my index.htm - with the latest news.htm included.

Any ideas?

Place this at the top of your page within the <head></head> tags, this will stop client side caching:

<HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE">

Although IE has a bug sometimes, to learn more read the microsoft article:

Good Luck

Ah ha - I think I've sussed it out...

Using <meta http-equiv="cache-control" content="no-cache"> in the HEAD seems to work.

Cheerz DeZiner - I must of posted my last reply about 5 seconds after your fix.
For those of you who are interested

From my understanding pragma is from HTTP1 and "cache-control" is from HTTP1.1 - is that correct.

http://www.vorb.org.nz

is served from a Cobalt RAQ (some flavour of Apache I guess)and seems fine with the "cache-control" angle

Does "cache-control" (or "pragma&quot

also prevent the caching of images - or is it just the HTML code?

Has even more info on preventing caching with MS products.
