Hallo, unfortunately it is a 404. And the 404 is only delivered when the request header contains "if-modified-since". If not the request is respondec correctly. This behaviour is reproducable.
Below you find an example of failed and successful request. The GET URL is in both cases http://localhost:8080/mywebapp/faces/static/META-INF/progressbar/script.js --> Failed Request (means tomcat responds with 404): Host: localhost:8080 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: de-de,en-us;q=0.8,de;q=0.6,en;q=0.4,fr-fr;q=0.2 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: JSESSIONID=262FAFFC220AF50656BC67C1C1DD1331 If-Modified-Since: Do, 17 Dez 2009 11:11:29 GMT Cache-Control: max-age=0 --> Response: Server: Apache-Coyote/1.1 Content-Type: text/html Content-Length: 1093 Date: Thu, 17 Dec 2009 11:24:38 GMT --> Successful: Host: localhost:8080 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: de-de,en-us;q=0.8,de;q=0.6,en;q=0.4,fr-fr;q=0.2 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: JSESSIONID=262FAFFC220AF50656BC67C1C1DD1331 Cache-Control: max-age=0 --> Response: Server: Apache-Coyote/1.1 Last-Modified: Do, 17 Dez 2009 11:11:29 GMT Content-Type: text/javascript Transfer-Encoding: chunked Date: Thu, 17 Dec 2009 11:24:53 GMT Does anybody have an explanation for this? Best regards, Abid -----Ursprüngliche Nachricht----- Von: Looijmans, Mike [mailto:mike.looijm...@oce.com] Gesendet: Mittwoch, 16. Dezember 2009 15:48 An: Tomcat Users List Betreff: RE: Ignore http header if-modified-since I assume you mean 304 (Not modified) instead of 404 (Not found). Simplest I can think of is to NOT put the "last-modified" header in your response. Then the browser won't send you an if-modified-since back. On the other hand, if you can put a datestamp on the response - e.g. a file date or by reading it from a DB or so - provide the proper response and you get client-side caching for (almost) free, which can seriously reduce load on a server.
