XC versions before 4.4.x do NOT have the ability to change skins. 4.4.x and above have multiple skins to chose from for the cart so if not default the skins is AltSkin....

Prior to 4.4.x there is only one skin in XC so thereis no AltSkin. Looking at your signature you have 4.1.11 so there is no AltSkin - you have to adjust the code and modify the lines in the file showing for your version

My signature shows that we are using 4.5.4 and that we upgraded from 4.1.11. It seemed important to show that we came from 4.1.11 while we were getting our site working with 4.5.4 correctly - I may remove the 4.1.11 from the signature now

I'm still unclear where the new assignments are being used though.

Oh sorry missed that...

They replace the calls in smarty.php

Thanks to all that contributed to post #57 - easy edits with powerful consequences.

Like others I was unable to do step #4 as the code was not present, but step #7 caught all images, apart from the product detailed image thumbnails. I had to make the following change:

File: /skin/common_files/modules/Detailed_Product_Images/colorbox_image.tpl

FIND:

<a href="{$i.image_url|amp}" class="lightbox"{if $config.Detailed_Product_Images.det_image_icons_limit gt 0 and $config.Detailed_Product_Images.det_image_icons_limit le $smarty.foreach.images.index} style="display:none;"{/if} rel="dpimages" title="{$i.alt|escape}"><img src="{$i.icon_url|amp}" alt="{$i.alt|escape}" title="{$i.alt|escape}" width="{$i.icon_image_x}" height="{$i.icon_image_y}" /></a> *}

REPLACE WITH:

      {* MaxCDN Replace with next line <a href="{$i.image_url|amp}" class="lightbox"{if $config.Detailed_Product_Images.det_image_icons_limit gt 0 and $config.Detailed_Product_Images.det_image_icons_limit le $smarty.foreach.images.index} style="display:none;"{/if} rel="dpimages" title="{$i.alt|escape}"><img src="{$i.icon_url|amp}" alt="{$i.alt|escape}" title="{$i.alt|escape}" width="{$i.icon_image_x}" height="{$i.icon_image_y}" /></a> *}
      <a href="{$i.image_url|amp}" class="lightbox"{if $config.Detailed_Product_Images.det_image_icons_limit gt 0 and $config.Detailed_Product_Images.det_image_icons_limit le $smarty.foreach.images.index} style="display:none;"{/if} rel="dpimages" title="{$i.alt|escape}"><img src="{$i.icon_url|amp|replace:'www.domain.com':'cdn.domain.com'}" alt="{$i.alt|escape}" title="{$i.alt|escape}" width="{$i.icon_image_x}" height="{$i.icon_image_y}" /></a>

For such small images the change made a huge difference, saving 0.88s on my test product page.

AltImagesDir and AltSkinDir were not present before the edit (unlike ImagesDir and SkinDir), so if they are new where are they being used? I'm guessing they are in fact used for your chosen skin, but that would mean the assignment exists elsewhere since it did not reside in smarty.php - in which case don't we need to delete the original assignment?

If I were using an XCart template then I would simply trust your post and include the code verbatim, but I'm using thexcartstore's xtreme_gear template and I've yet to workout how to include their template resources on CDN. It's complicated more because I have a different template for mobiles - so I'm not sure what to put for AltImagesDir and AltSkinDir.

And I am now understanding your confusion...
I am also confused, now that I have two active skins.
Which skin is $AltSkinDir (xtreme or xmobile?)

I am also seeing the txs templates and modules not use the default calls that automatically send content to the cdn. So I am having to figure this out.

What is the solution for step #4 if you have two active skins?

Using Vivid Dreams as a substitute for books_and_magazines, , I have the strange problem where I can get images to show in https but not in non-secure mode http using this code:

// MaxCDN - next two lines commented out
//$smarty->assign('ImagesDir', $xcart_web_dir . $smarty_skin_dir . '/images');
//$smarty->assign('SkinDir', $xcart_web_dir . $smarty_skin_dir);
// MaxCDN add the following
if ($_SERVER['HTTPS'] != 'on')
{
$smarty->assign('ImagesDir', "http://cdn.domain.com" . $smarty_skin_dir . '/images');
$smarty->assign('SkinDir', "http://cdn.domain.com" . $smarty_skin_dir);
$smarty->assign("AltImagesDir", "http://cdn.domain.com/skin/books_and_magazines/images");
$smarty->assign("AltSkinDir", "http://cdn.domain.com/skin/books_and_magazines");
}
else
{
$smarty->assign('ImagesDir', $xcart_web_dir . $smarty_skin_dir . '/images');
$smarty->assign('SkinDir', $xcart_web_dir . $smarty_skin_dir);
}
// END MaxCDN edit

Any clue why it wouldn't show up in non-https mode? If I keep the original code, however, images show but not through MaxCDN of course.

When I try to call up an individual image in a new tab, I get a "403 Forbidden" notice...

Stating the obvious?
substitute
vivid_dreams_lotus
for
books_and_magazines

?

[kevinrm]

Yes, of course I replaced those.

I'm having a very difficult time getting this to work with 4.6.0. Even the basic thumbnails are giving me a 403 Forbidden error when I try to get them to load them from MaxCDN:

cdn.domain.com/images/T/image123.png

(NOTE: I had several referrers in the MAXCDN control panel - don't put referrers in there! )

[Kman]

I am having a devil of a time getting css and js files to load from the CDN in 4.6.1.

I have patched function.load_defer_load.php appropriately (Thanks Phil!), but it looks to me that the issue (for css) is in customer/service_css.tpl and customer/service_css_modules.tpl. The path to the css files there are relative from the root of the store - not complete: xx/skin/..../zz.css rather than {$SkinDir}/..../zz.css.

The result is that the redirection to the CDN in defer_load never takes place. There is no code among all of the various patches that will pick this up - everything depends on seeing {$SkinDir} or {$AltSkinDir}.

Has anyone figured this out? I suppose I could hard code the paths to all of the various modules using the {$SkinDir} abd {$AltSkinDir} constructs, but that seems too much like brute force.

I have not looked at the .js file load, but I'm betting it is somewhat similar.

A side effect of this is that if I turn on the internal X-Cart optimization for js or css, none of these files load at all.

I'll post a complete version of the solution once we (com on, let's do this together) get it right.

I'm still having a difficult time implementing MAX-CDN & XC with regards to generated thumbnails in HTTPS mode. I want it to load from MaxCDN in non-secure http mode, and to not load from MaxCDN in https mode.

Chrome is showing a yellow lock because of this and customers are bugging me about it, I need to get this figured out.

According to MAX-CDN implementation instructions for XC…

Utilize CDN for “W”, “D”, “P” and “T” types of images:

1) Open /include/func/func.files.php and find the following line:

global $config, $sql_tbl, $xcart_dir, $current_location;

2) ADD these new lines below (DON’T replace with but ADD below it):

if ($HTTPS)
$current_location = $current_location;
else
$current_location = 'http://netdna.domain.com';

When I try to do this insecure in HTTP, it correctly generates this kind of URL for thumbnails: http://netdna.domain.com/images/T/16580t.jpg

When I try to do this in HTTPS mode, it should revert back to https://www.domain.com/images/T/16580t.jpg

However, it doesn't, I get this error:

The page at 'https://www.domain.com/home.php' was loaded over HTTPS, but displayed insecure content from 'http://netdna.domain.com/images/T/16580t.jpg': this content should also be loaded over HTTPS.

In step 4 of post #57, the code "$current_location = $current_location; " does not exist in more recent versions of /include/func/func.files.php

I've tried both Max CDN version method as well as the method shown in post #57, same error.

Anyone got this working on a more recent version of XC?
