Re: FLASH: IE-cache, text file

[John Croteau]

Hi all,


To prevent caching by sending an HTTP Header from the server, there

seems to be two different techniques depending on the server software.

In IIS 4.0 you can easily set the headers 

by file or directory, but in Apache you cn designate a file extension

for this purpose and have a server wide solution.


----------------------------------------------------------------------------


In Microsoft IIS 4.0 you can easily send "Content to expire immediately"

in the HTTP Headers. If you don't have access to the server create a

special directory and ask the administrator to set a special HTTP Header

for that directory.


To set server side HTTP Header 'Content Expiration' for a file or

directory in Microsoft IIS 4.0:


1) Go to Micrrosoft Management Console

2) Select the directory or file under the appropriate HTML Web server,

right click and select Properties.

3) Select HTTP Headers Tab

4) Check the box Enable Content Expiration

5) Select either Expires immediately or Expires on with an old date.

6) Select OK

In Apache or similar server you might want to designate (or create) a

new text/plain file extension (such as txxt), set the MIME for it and

then set the http.conf file with something like this:


<Files "*txxt">

Header append Pragma "no-cache"

Header set Cache-Control "no-cache"

</Files>


This would make files such as money.txxt act like any other plain text

file but would prevent them from being cached.
