browser cache issue SAP UI5

Former Member — Fri, 09 Jan 2015 10:12:48 GMT

Hi ,

I have developed a SAP UI5 application and moved it to the production server. subsequent to that i have made some changes to the code in development server and moved it to production server. But when we access SAP UI5 application from the browsers the new code is not getting updated in the application. To make this work every time i need to clear the browser cache manually. Even after running the report " " we need to clear cache in the browser manually.

In the application index we are using this code

<script

src="resources/sap-ui-core-all.js"

id="sap-ui-bootstrap"

data-sap-ui-libs="sap.m, sap.ui.commons, sap.suite.ui.commons, sap.ui.table, sap.ui.ux3,sap.viz"

data-sap-ui-theme="sap_bluecrystal"

data-sap-ui-appCacheBuster="./" >

</script>

Please suggest how make the new code getting reflected in the browser without clearing the browser cache manually.

Thanks & Regards,

Jayasree.

if your code does not work, disable the browser cache.

In chrome => F12 => Network => Disable cache.

As developer I never use caching in my browser.

you can do what Kai has said or

you can switch to in-cognito(Ctrl+Shift+N) mode if you are using chrome.

In this mode browser will never cache.

For a production solution you should look at the cache buster mechanism.

The mechanism changes the URL to prevent browser caching issues.

Cache Buster - UI Frameworks based on HTML5, JavaScript and CSS - SAP Library

Application Cache Buster - UI Frameworks based on HTML5, JavaScript and CSS - SAP Library

Clearing/disabling caching is fine for testing, however Jayasree mentioned deploying to production, where you can't rely on user clearing their cache.

Hello ,

In web.xml do following changes:

inside :

<context-param>

Add:

<param-name>com.sap.ui5.resource.DEV_MODE</param-name>

<param-value>true</param-value>

</context-param>

Again, this is ok for development, however the question related to production where you shouldn't enable the dev mode.

Right then also include the code :

<display-name>AppCacheBusterFilter</display-name>

<filter-name>AppCacheBusterFilter</filter-name>

<filter-class>com.sap.ui5.resource.AppCacheBusterFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>AppCacheBusterFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

That's what I recommended above, obviously will be different if you are not using a Java stack.

Hi,

This problem occurs in Microsoft Internet Explorer. However, in case of MS Explorer 10, the problem can be sorted out in the following way -

Go to Settings --> General --> Browsing History --> Settings

and please select the following option -

Check for the newer versions of the stored webpages -

Every time I visit the webpage

This will work and every time it will give refreshed version of the webpage only.
