Is there any documentation for the configuration of the mime-type of those .mhtx files?

.mhtml is defined as message/rfc822

Sharepoint’s mhtx is defined as text/plain.

Is there any doc about that extension (can’t find it on Google)

Thx!

I conducted a study how works the Aptimize for IE7@Vista.
All MHTML files is not cached for IE7@Vista. Each image in mhtml re-download the entire mhtml. it’s anti-optimizations for IE7@Vista!

@Schepp, Forgive me, if I have somehow offended for you.

@sunnybear already spoken with representatives of Microsoft – at the out ZERO result.

Once again, you want to point out the fact that it is useless fixes Vista @ IE7 + MHTML. After rebooting MHTML images disappear.

I am very shocked that there is no normal solution.

@Ruslan I didn’t mean to make it interesting. I did mean to fix this broken look.

For the type of bugfix you are thinking about, grab your phone and call Microsoft.

@Schepp, Ha-ha! how you solved problem? added standard background-image?

.div1:hover{background-image:url(/booster/./../testcases/testcase1/css/../images/hoverstate.gif);color:#66F}

this solving is not interesting.

And after reload page – background is WHITE (not blue) = after page reloading MHTML not works.
Sorry, but Vista@IE7 + MHTML is incompatible.

@Ruslan I fixed the bug by skipping MHTML-ification of background-images on :hover-selectors. Tested on a virtual maschine with Vista and IE7.

If you happen to redownload my package on GitHub: I moved the testcase into /testcases/testcase1/index.php

A sincere thanks for this post Steve. We have been hard testing Aptimize for the past 4 days and I would like to tell you that the results have been nothing short of amazing. 42% increase in first page load time – 51% increase in repeat page laod time. The software also appears to have fixed a significant caching issue that we have been scratching our heads about for the past three months. We have further testing to do but I just wanted to send my regards for bringing this to our attention.

@sunnybear, I don’t think that the mix of data:URI+mhtml with standart CSS Sprites is the best idea. I think after some time the CSS sprites become extinct like the dinosaurs. data:URI it’s killer of CSS sprites, not friends :).

@Ruslan, @Schepp: I think that the best solution is in the right combination of mhtml, data:URI, and CSS Sprites approaches. Each of these techniques is great, so their combination will be killer-feature. Also we can just exclude images from mhtml/data:URI processing to prevent such side effect.

@Ruslan Not so good to hear. The problem is that I currently don’t have such an exact setup at my hands to test that out myself. Thinking about skipping MHTML-ification of all :hover-selectors now… Anyhow, thank you for your input on this specific “bug”. Wouldn’t have found out myself for some time!
