AJAX i network latency

[ivanhoe]

Ne znam da li ste vec videli, ali ko nije, a planira da koristi AJAX widgete nek pogleda obavezno:

showcase problema koji mogu da nastanu zbog kasnjenja izmedju klijenta i servera (a koja su neizbezna, narocito u Srbiji..).

E a kad pogledate primer, setite se price koja je i ovde pominjana, a inace se puno ljudi lozilo na to, o tabelama cije se izmene live snimaju u bazu kako korisnik kuca. Brrrr...:1027:

Mislim da sam ovaj link vec postovao na forumu, to je inace i predavanje koje je HF drzao na Londonskoj konferenciji. http://www.sitepoint.com/blogs/2006/02/10/ajaxlocalhost/

Ako se moze (npr. slike) uvek je bolji preload. Tek ako zaista treba ajax (jer ja vidim i sajtove koje ajax koriste na DHTML menijima!) onda moze. Problem nije samo u Srbiji (gde su latencije reda 100-300ms) vec i ako imate posetiooce sa drugog kontinenta (server u Japanu, posetilac iz Argentine...)

hehe, mator sam, oslabilo pamcenje :)

Ali kad sam vec postovao, jel koristio mozda neko ovaj python proxy za simuliranje kasnjenja ? To mi deluje kao zanimljiva igracka, doduse kod nas ne mora da se simulira, kod nas je to realnost :D

jel ovo reshenje problema ?

3/11/2006 - Submission Queue Added

With release 0.5 I've added by default a throttling queue for all AJAX requests. Some call it a "command queue". This will keep all your request/responses in sync with each other. For example, let's say you had two links on your page, one click took 3 seconds on the server and the other only took 1 second to reply. Previously and in normal AJAX requests those would have wiped each other out. Now your request is queued so that when the first request is finishes it will automatically take the next one in the queue by order in which they were receive. Check out a working sample here: http://www.litfuel.net/mybic/throttle.html
