Do not cache custom FAQ component

[dipu2]

Dear All,

I have one page called sunita.html and some components are there like text , title etc with my custom component FAQ.

My requirement is that whenever end user will hit the page sunita.html then my custom component FAQ will not be cached. I have used sling dynamic include and done the below steps and still this is not working.

**********************Dispatcher.any*********************

/rules
{
/0000
{
# the globbing pattern to be compared against the url
# example: * -> everything
# : /foo/bar.* -> only the /foo/bar documents
# : /foo/bar/* -> all pages below /foo/bar
# : /foo/bar[./]* -> all pages below and /foo/bar itself
# : *.html -> all .html files
/glob "*"
/type "allow"

/nocache {
/glob "*.nocache.html*"
/type "deny"
}
}
}

Hi , My issue is still there..Can you please mark this again an question "or" can I create a new thread ?

Hello @dipu2 ,

First of all, could you please confirm that on your Publish instance the bundle "Apache Sling Dynamic Include" is installed, the corresponding configuration for "Apache Sling Dynamic Include - Configuration" is set, and you see the similar comment in source code of the page close to your component (due to the "Add comment" checkbox in the config):
<!-- SDI include (path: /content/we-retail/language-masters/en/user/mailbox/_jcr_content/root/responsivegrid/text.nocache.html, resourceType: weretail/components/content/text) -->

If the comment is missing, the configuration on Publish should be double-checked prior to digging into Dispatcher configs.

Regards

Thanks Andrei,

Previously , I did not install the bundle "Apache Sling Dynamic Include" in my publish instance (localhost:4503)...But Now I have installed and changed accordingly below.

After Changed in the "dynamic include config" in publisher , I am able to see the comments in my html file like below.

<div class="faq aem-GridColumn aem-GridColumn--default--12"><!-- SDI include (path: /content/referencesite/us/en/faq/_jcr_content/root/container/container/faq_1189772069.nocache.html, resourceType: sunita/components/faq/v1/faq) -->
<!--#include virtual="/content/referencesite/us/en/faq/_jcr_content/root/container/container/faq_1189772069.nocache.html" --></div>

But , I am not able to see my FAQ value in the website , as shown below.

But I am able to see the FAQ value in my publish instance , as shown below.

Is there anything I am missing ?

@dipu2,

As far as I can see on the screenshots, the page on Dispatcher was cached previously ("faq" page title is present on Dispatcher, and it's missing on Publish).
Could you please try to clean the Dispatcher cache for this page and re-check?

[Andrei_Dantsou]

@dipu2,

If the component is still not shown, please make sure that all the steps from the section Enabling SSI in Apache with the AEM Dispatcher Module have been applied on the Dispatcher.
In particular, can you please double-check this:

Also could you please confirm that mod_include is enabled?
LoadModule include_module modules/mod_include.so

[Jörg_Hoh]

First of all, you configured SSI to be active only files with the extension ".shtml". You can either reconfigure AEM a bit to handle that extension as well, or you can just change the configured extension to ".html"; it will add a small overhead to each HTML request, but that's probably not a problem in the first place.

Then please describe, what you mean "it is still not working"? Is that FAQ component missing in the rendered HTML?

[dipu2]

Hi Andrei and Jörg_Hoh,

Dear all, I tried all the steps , but still my FAQ component is not displaying and did below steps.

I am using Apache 2.2 and followed the below adobe help document and configured my dispatcher for SDI.

https://docs.adobe.com/content/help/en/experience-manager-learn/foundation/development/set-up-sling-...

I have changed my httpd.conf like below.

# ***********************************
# Adobe CQ5 Dispatcher Configuration

# Dispatcher Configuration

And I have added below (in red text) in my dispatcher.any file.

# : *.html -> all .html files
/glob "*"
/type "allow"

/nocache {
/glob "*.nocache.html*"
/type "deny"
}
}

After changing  the configured extension to ".html" , I am getting below error.

Can you please help me on this ?

[Andrei_Dantsou]

Hi @dipu2,

As per your previous message, the resource on Publish is <!--#include virtual="/content/referencesite/us/en/faq/_jcr_content/root/container/container/faq_1189772069.nocache.html" --></div>, whereas on Dispatcher the path is /content/referencesite/us/en/faq/_jcr_content/root/container/container/faq.nocache.html.
The path to the included resource should be the same on both Publish and Dispatcher.

My guess is that Dispatcher has cached page html containing improper path (e.g. during intermediate configuration). Can you please try to clear Dispatcher cache for /content/referencesite/us/en/faq and re-check the page on Dispatcher? In addition, can you please ensure that the same path is contained in page html source on both Publish and Dispatcher in the following comment (placed right before your component):
<!-- SDI include (path: /content/referencesite/us/en/faq/_jcr_content/root/container/container/faq_1189772069.nocache.html, resourceType: sunita/components/faq/v1/faq) -->

Thanks Andrei,

I have deleted faq from my dispatcher cache and again requested.

In my publish instance I am seeing below.

<div class="faq aem-GridColumn aem-GridColumn--default--12"><!-- SDI include (path: /content/referencesite/us/en/faq/_jcr_content/root/container/container/faq.nocache.html, resourceType: kf/components/faq/v1/faq) -->
<h1> FAQ Component </h1>

<div>sunita testing for dispatcher config</div></div>
<div class="image aem-GridColumn aem-GridColumn--default--12">
</div>

But in my dispatcher , I am seeing below.

</div>
<div class="faq aem-GridColumn aem-GridColumn--default--12"><!-- SDI include (path: /content/referencesite/us/en/faq/_jcr_content/root/container/container/faq.nocache.html, resourceType: kf/components/faq/v1/faq) -->
<!--#include virtual="/content/referencesite/us/en/faq/_jcr_content/root/container/container/faq.nocache.html" --></div>
<div class="image aem-GridColumn aem-GridColumn--default--12">
</div>

But , I observed one thing that in my dispatcher.log file I am getting below error.

[C:\Users\sunita_c\Sunita-Work\AEM-LOCAL-ENVIRONMENT\DISPATCHER\cache\.stat] -> use cache

Hi @Andrei_Dantsou, Now my issue is fixed and coming fine after adding below in my conf file.

<Directory C:/Users/sunita_c/Sunita-Work/AEM-LOCAL-ENVIRONMENT/DISPATCHER/cache>

<IfModule disp_apache2.c>
SetHandler dispatcher-handler
ModMimeUsePathInfo On
</IfModule>

Options FollowSymLinks includes
AllowOverride None

AddOutputFilter INCLUDES .html

# Apache httpd 2.2
Order allow,deny
Allow from all
</Directory>
