Different values in signatures

Postby m80falcon » Thu Jul 13, 2006 11:39 am

Hi,

Due to a safe_mode error I discussed in another thread already, I have to use the following link to use the signature in forums

Code: Select all
http://wow.mighty-force.de/addons/siggen/sig.php/esaria.png


This displays the following signature :

But it doesn't show the actual values. If I look at the signature with the following link it displays different values (the true ones for EP) :

Code: Select all
http://wow.mighty-force.de/addons/siggen/siggen.php?name=Esaria&mode=signature

How do I get the right values in the first version ?

They look identical to me. Maybe your browser is caching the first one, since it thinks it's a (static) image?

safe_mode doesn't effect this in any way
safe_mode only affects uploading of custom user images, that's it

As for images being cached
SigGen uses what is called e-taging to tell the browser that it can cache the results of this php script
You can turn this action off in SigGen Config so it will always fetch a fresh image (This is what the preview window in SigGen config does as well, it adds "&etag=0" to the end of the image to turn etag off)

You browser sees these as separate images
Code: Select all
http://wow.mighty-force.de/addons/siggen/sig.php/esaria.png
http://wow.mighty-force.de/addons/siggen/siggen.php?name=Esaria&mode=signature

Both of which are still accessing siggen.php (sig.php is just a front end for siggen.php)

The top line is still accessing a php script, it just tricks certain forum software into thinking its an image (because of the .jpg at the end)

Heh, I just barely "solved" this one by myself. Too bad I didn't just read zanix' explanation first.

Ya know, you may want to change the default config of SigGen to turn e-tag off. Might help eliminate future posts of problems like this.

As soon as the user updates their data, the etag is reset and a new image is fetched anyway

Isn't this only the case if you update via the site, and not the UniUploader? (And of course, have that option turned on in SigGen.)

I'm anxious to get to where I can turn etag caching back on yet still have character images update with changes. I've noticed since I turned it off that images will occasionally "hang" in a perpetual loading state. It's kind of obnoxious when you're viewing a series of posts and everyone has an image in their signature. Seems at least one hangs each page load.
