My website has Home page speed problem, (The home page is loading so many CSS and JS files by the theme and attached plugins) , I'm trying to fix it and also I came up with the following htaccess caching codes which solved some of the problem, after using this code, I had a problem with the admin backend caching system, the modification refresh function is not working, but when I delete the codes in htaccess file things back to normal... My question is

1- How to exclude the admin backend from this code and is this completely correct code for my website to use?

2- My website is https and has two themes (desktop and mobile theme), https:www.website.com/index.php?route=common/home was redirected to https:www.website.com with an extension which did the job. Mobile theme's original url is: "/index.php?route=extension/mobile/home" I want to make it into "https://www.website.com/mobile"

P.S:Using Opencart Version 3.0.3.2

Any help & correction is appreciated
By the way the advices were given by IP_CAM on this artical viewtopic.php?t=207490 are very helpful..thanks for him! :)

the htaccess code that i have:

Code: Select all

# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.

# 2. In your opencart directory rename htaccess.txt to .htaccess.

One simple way would be, to implement all CSS File Content
into the default stylesheet.css, and then compress that file.
Then, you just have to remove all the links, directing to the formerly
individual CSS Files, whereever they exist.
As well as compressing all the existing JS Files individually as well:
https://www.giftofspeed.com/tools/
You then get a one-liner stylesheet.css file as result of this, and most JS
Scriptings can be compressed the same way. Some can even be 'combined' into
one file too, but that's a little more complicated, just to have it mentioned too ... :D
And if you do it right, it will end up in a speedy one-liner Source, as it can be seen here:

Make sure there is a .htaccess file in your admin folder.
it can be empty.

Setting the expires header for responses from PHP can cause problems at checkout, especially in some browsers.

You might as well just start again with a decent theme like:

i already did compressed most of the CSS and JS files, but i'll try to combine files, it may help..
I have seen your reply in this post for an older version of opencart, but # Leverage Browser Caching is causing the problem in checkout page. :(

The admin directory is without htaccess file by default, as you mentioned that i have to add htaccess file in admin dir, what codes should i put in? i may give it a try, but the problem i think can still be existed for the checkout page. :(

Yes, correct, it causes problems in checkout and switching between payment and shipping methods, i tried the way was mentioned in the post you suggested, it worked the same as before, as there is not caching codes in htaccess. :-\

I may try it in future because the theme that i'm using now already got custom modifications and it's hard to transfer them to a new theme. :)

The problem that I found was in this piece of code only:

Code: Select all

# Leverage Browser Caching
<IfModule mod_expires.c>
 ExpiresActive On
 ExpiresByType image/jpg "access plus 1 week"
 ExpiresByType image/jpeg "access plus 1 week"
 ExpiresByType image/gif "access plus 1 week"
 ExpiresByType image/png "access plus 1 week"
 ExpiresByType text/css "access plus 1 week"
 ExpiresByType application/pdf "access plus 1 week"
 ExpiresByType text/x-javascript "access plus 1 week"
 ExpiresByType application/x-shockwave-flash "access plus 1 week"
 ExpiresByType image/x-icon "access plus 1 week"
 ExpiresDefault "access plus 1 week"
</IfModule>
The good thing of this code is that it loads pages so fast for the second time browsing, which I need it especially in my mobile theme, when users browsing on mobiles.
I tried this cache-control code instead and it worked fine, also the Checkout process was working without issues, BUT pages weren't loading as fast as Leverage caching code.

Code: Select all

# 1 Month for most static assets
<filesMatch ".(css|jpg|jpeg|png|gif|js|ico)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>

You need both the bug fix to system/framework.php and your ExpiresByType/ExpiresDefault in htaccess. That way all static files will be cached, but dynamic PHP responses won't.

if you have a .htaccess in your root folder, it will pass everything in that file to any folder.
in your case your caching a lot og things and that also applys to your admin folder.
if you plave a .htaccess file in your admin folder it wont follow rules from your root.
.htaccess file does nit have to contain any lines, just leave it emty.
