Internal Server Error – htaccess


I have a htaccess file that it work perfectly on host but when I put it on local ,it shows me this error:

Internal Server Error

The server encountered an internal error or misconfiguration and was
unable to complete your request.

Please contact the server administrator, admin@localhost and inform
them of the time the error occurred, and anything you might have done
that may have caused the error.

More information about this error may be available in the server error

I found this alert in error log file :

[Tue Apr 17 10:02:25 2012] [alert] [client] D:/wamp/www/jivan/sql/.htaccess: Invalid command 'Header', perhaps misspelled or defined by a module not included in the server configuration

this is my htaccess file code:

  RewriteEngine On
AddDefaultCharset utf-8
RewriteRule ^([0-9-]+)/keyword_show.html$ keyword_show.php?keyword_id=$1
RewriteRule ^page_(.*).html$  page.php?url=$1
RewriteRule ^([0-9-]+)/(.*)/(.*)/(.*).html$ $2.php?advertisement_cat=$1&id=$3&pagenumber=$4
RewriteRule ^([0-9-]+)/(.*)/(.*).html$ $2.php?advertisement_cat=$1&pagenumber=$3
RewriteRule ^([0-9-]+)/(.*).html$ $2.php?advertisement_cat=$1
# cache images and flash content for one month
<FilesMatch ".(flv|gif|jpg|jpeg|png|ico|swf)$">
Header set Cache-Control "max-age=2592000"

# cache text, css, and javascript files for one month
<FilesMatch ".(js|css|pdf|txt)$">
Header set Cache-Control "max-age=2592000"

my local server run by wamp and I enabled rewrite module too!!!

so what`s the prob?!!

Best Solution

the Header directive is in the mod_headers apache module. You need to make sure that module is loaded into the apache server.
