different count of ocsp-POST-requests
Hi,

we noticed a different number of (unfortunately very expensive) ocsp-requests shown in waterfalls delivered by version 126 and 130 of wptdriver. We tested with actual Firefox the following script:

Code:
logData    0
setCookie    http://www.otto.de    uniqueUserId = 806fd6a9-82e9-4f22-b1c0-ee262f1c4cfa; expires = 01-Jan-2080 00:00:00 GMT
/// Produkt 1 in Warenkorb
navigate    http://www.otto.de/suche/?commit=true&ls=0&commit=true&fh_search=shirt&&fh_search_requested=shirt&sterm=shirt&stype=N
execAndWait    document.querySelector('#p0 a.js_ProductListProductRef').click();
execAndWait    document.getElementById('TconImgAddToBasket').click();

/// Produkt 2 in Warenkorb
navigate    http://www.otto.de/suche/?commit=true&ls=0&commit=true&fh_search=brille&&fh_search_requested=brille&sterm=brille&stype=N&SelectRuleEngineVariants=0
execAndWait    document.querySelector('#p0 a.js_ProductListProductRef').click();
execAndWait    document.getElementById('TconImgAddToBasket').click();

/// PRodukt 3 in Warenkorb
navigate http://www.otto.de/suche/?commit=true&ls=0&commit=true&fh_search=bikini&&fh_search_requested=bikini&sterm=bikini&stype=N&SelectRuleEngineVariants=0
execAndWait    document.querySelector('#p0 a.js_ProductListProductRef').click();
execAndWait    document.getElementById('TconImgAddToBasket').click();

/// PRodukt 4 in Warenkorb
navigate    http://www.otto.de/suche/?commit=true&ls=0&commit=true&fh_search=adidas&&fh_search_requested=adidas&sterm=adidas&stype=N&SelectRuleEngineVariants=0
execAndWait    document.querySelector('#p0 a.js_ProductListProductRef').click();
execAndWait    document.getElementById('TconImgAddToBasket').click();

/// Produkt 5 in Warenkorb
navigate    http://www.otto.de/suche/?commit=true&ls=0&commit=true&fh_search=nike&&fh_search_requested=nike&sterm=nike&stype=N&SelectRuleEngineVariants=0
execAndWait    document.querySelector('#p0 a.js_ProductListProductRef').click();
execAndWait    document.getElementById('TconImgAddToBasket').click();

logData    1
execAndWait    document.getElementById('TconImgGotoBasket').click();

In wptdriver 126-tests we had much more ocsp-requests than in actual wptdriver 130-tests (see hars in attachments). We think (and observed in wireshark manually) that wptdriver 126-results are more realisitic.
Could you tell us, what changes between 126 and 130 could be responsible for this. And what changed in measurement of HTTPS-sites with wptdriver the last weeks?

Thanks in advance,
regards, Nils

RE: different count of ocsp-POST-requests
I'm fairly certain that the only change that should impact any of that was that the navigation command in scripts was pretty broken in 126 and it was fixed in 130.

The other thing that changed was that Firefox 23 was released - just a quick sanity check, were both sets of tests on the same Firefox version? Also, were you using the stock template/firefox directory from the release or had you pre-seeded any certificates?

Here is the full diff between the two releases: https://github.com/WPO-Foundation/webpag...b7caa11293
