"same content" for images?

Hi,

I'm trying to speed up my pages, and for some reason I keep getting this coming up:

The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 49.2KiB.

The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 47.6KiB.

The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 41.3KiB.

Seems a bit silly to keep re-downloading the same images? (I checked them, and they are indeed identical) ... is there any way to stop this?

TIA!

If Google would stop this your maps would be loading slower.

The browsers do fetch only a few images simultaneously from one URL.
To bypass these browser restrictions the map tiles are loaded from
different URLs.

It's a good trick imho.

Browsers open a limited number of connections to a particular server,
eg mt0.google.com, mt1.google.com, and so on. This is why tiles are
fetched in a "checkerboard" pattern.

However, the images which Andy referred to differ only in a parameter
in the url -- they are fetched from the same server. There seems no
good reason to do that when it will frustrate the browser cache.

Hi,

Yeah, I'm aware of using different URL's to help speed the pages up (I do that myself on sites)... but as you say, the image is IDENTICAL, and the URL just differs with stuff like this in it:

http://mt0.googleapis.com/vt?lyrs=m@156&src=apiv3&hl=en-GB&x=66&y=43&z=7&apistyle=s.t%3A33|s.e%3Al|p.v%3Aoff&s=G
http://mt0.googleapis.com/vt?lyrs=m@156&src=apiv3&hl=en-GB&x=66&y=43&z=7&s=G

The first one has an extra "apistyle=s.t%3A33|s.e%3Al|p.v%3Aoff" in it, which doesn't seem to make a difference?

I was just more concerned I was doing something silly like invoking it 2 times or something, but by the sounds of it this is common prachive for v3?

TIA

Andy

Hi Andy

Thanks for reporting this - we'll be taking a look at this internally.

Might I confirm with you which version of the API are you using? (3.3, 3.4 or 3.5?)

Hi,

Thanks, that would be great. I'm not actually sure what version I'm using? I just have:

<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>

...and no v=xxx

TIA

Andy

FYI - that is the "nightly" (development) version:

Ah ok, so in fact I should actually be accessing it via v=3.5 (or whatever version I wanna use) ?

Production pages should never use the "nightly" (development) version,
it can break unexpectedly.

Not also that the "Frozen" version will be retired the next time a new
current version comes out, so you probably don't want to be using that
either.

Aah ok, I wasn't aware of that. Thanks for the heads up. I'll get that changed over ASAP :)
