How to show Last Modified date in every pages through out the portal

[Anuvab Ghosh，修改在8 年前。]

I have a requirement to show Last Modified/Updated date in every page through out the Liferay portal. It should be updated with respect to any modification in the page (Web Contents / Portlets, anything). How is it possible? please explain me. I am new in Liferay and using Liferay 6.1.1. ce/ee ga2. Please share your ideas with me and give the solutions. It is very urgent for me.

Thanks in advance.

It doesn't matter how many times you guys post the same question, but it's not going to be possible.

Liferay aggregates individual portlet contents into a single page. So a page "last modified date" really doesn't make any sense. For dynamic portlets, the content changes all the time so last update makes no sense.

Hi Anuvab,

Liferay uses a CacheFilter which stores a page content in a cache for pages that meets some conditions.

I'd recommend you to investigate the usages of

CacheUtil.clearCache() 

and

CacheUtil.clearCache(long companyId) 

through all Liferay source code to see when pages portlets are modified (Layout) and there you could update the page modified date so it can be seen in every page.

Hope it helps....
