RE: Publication date

Ok !

I've done that and everything goes well ! For your interest, the following codes are the solution I've use (in order templates adding code / patch on jahia / apache conf).

I've put the new HtmlCacheEntry in webapps/jahia/WEB-INF/classes directory, modify the jahia.properties to add the property "readonlyserver" and restart the server.

TEMPLATES

Here is the code I had in header.inc (after the include of declarations.inc) :
<%
// Definition des headers en fonction des droits des utilisateurs
// Si on est en anonyme ou que le serveur est utilisé en lecture uniquement --> utilisation du cache Apache
if (!jData.gui().isLogged() || bIsReadonlyServer)
{
  int iCacheMaxExpire = 24*3600; // 24 heures max pour cache Apache
  // Get the language code
  String curLanguageCode = LanguageCodeConverters.localeToLanguageTag(jParams.getLocale());
  // Extract the workflow state out of the parameters bean
  int workflowState = jParams.getEntryLoadRequest().getWorkflowState();
  // Get the HTML cache instance
  HtmlCache htmlCache = CacheFactory.getHtmlCache();
  // Get the CacheEntry
  String entryKey = htmlCache.computeEntryKey(Integer.toString(jParams.getPageID()),
  jParams.getUser().getUsername(), curLanguageCode, workflowState, jParams.getUserAgent());
  Date dLastModifiedCacheDate = new Date();
  try {
    CacheEntry cacheEntry = (CacheEntry)htmlCache.getCacheEntry(entryKey);
    HtmlCacheEntry htmlEntry = (HtmlCacheEntry) cacheEntry.getObject();
    dLastModifiedCacheDate.setTime(htmlEntry.getContentTimestamp());
  } catch(Exception e) {}
  Date dExpires = new Date();
  dExpires.setTime(dLastModifiedCacheDate.getTime() + iCacheMaxExpire);
  logger.debug("Header Expires = " + getDateAsRFC822String(dExpires));
  logger.debug("Header Last-Modified = " + getDateAsRFC822String(dLastModifiedCacheDate));
  logger.debug("Header Cache-Control = " + "max-age=" + iCacheMaxExpire + ", must-revalidate");
  response.addHeader("Expires", getDateAsRFC822String(dExpires));
  response.addHeader("Last-Modified", getDateAsRFC822String(dLastModifiedCacheDate));
  response.addHeader("Cache-Control", "max-age=" + iCacheMaxExpire + ", must-revalidate");
}
// Autrement --> pas de cache Apache
else 
{
  Date dExpiresAbsolute = new Date();
  dExpiresAbsolute.setTime(dExpiresAbsolute.getTime() + 24*3600);
  logger.debug("Header Cache-Control = no-cache");
  logger.debug("Header Pragma = No-Cache");
  logger.debug("Header ExpiresAbsolute = " + getDateAsRFC822String(dExpiresAbsolute));
  logger.debug("Header Expires = -1");
  response.addHeader("Cache-Control", "no-cache");
  response.addHeader("Pragma", "No-Cache");
  response.addHeader("ExpiresAbsolute", getDateAsRFC822String(dExpiresAbsolute));
  response.addHeader("Expires", "-1");
}
%>
Here is the code I had in declarations.inc :

private static PropertiesManager properties = new PropertiesManager(Jahia.getJahiaPropertiesFileName ());
private boolean bIsReadonlyServer = "true".equals(properties.getProperty("readonlyserver"));

public static SimpleDateFormat RFC822DATEFORMAT = new SimpleDateFormat("EEE', 'dd' 'MMM' 'yyyy' 'HH:mm:ss' 'Z", Locale.US);
public static String getDateAsRFC822String(Date date)
{
  return RFC822DATEFORMAT.format(date);
}

PATCH JAHIA 4.0.6

Here is my personnal org.jahia.services.cache.HtmlCacheEntry (in red the code I've had) :

public class HtmlCacheEntry implements Serializable {

    /** the HTML body content. */
    private String contentBody = "";

    /** the HTML content type. */
    private String contentType = "";

    /** the date of HTMLCacheEntry creation / update **/
    private long contentTimestamp = -1;

    public HtmlCacheEntry (String contentBody) {
        init (contentBody, null, new Date().getTime());
    }

    public HtmlCacheEntry (String contentBody, String contentType) {
        init (contentBody, contentType, new Date().getTime());
    }

    private void init (String contentBody, String contentType, long contentTimestamp) {
        if (contentBody != null)
            this.contentBody = contentBody;
        if (contentType != null)
            this.contentType = contentType;
        
        this.contentTimestamp = contentTimestamp;
        
    }

    final public String getContentType() {
        return contentType;
    }

    final public void setContentType (String contentType) {
        this.contentType = contentType;
        this.contentTimestamp = new Date().getTime();
    }

    final public String getContentBody() {
        return contentBody;
    }

    final public void setContentBody (String contentBody) {
        this.contentBody = contentBody;
        this.contentTimestamp = new Date().getTime();
    }

   final public long getContentTimestamp() {
       return contentTimestamp;
   }
}

Then in Apache, I've had a new virtual site declaration for my site

<VirtualHost *:80>
  ServerName www.mysite.mydomain.fr
  # Logging access
  CustomLog "|/apache/2.0.54/bin/rotatelogs /apache/logs/jahiaconsult_access_mysitekey_log.%Y-%m-%d-%H_%M_%S.log 86400" common
