[pokal4u]

Hi,

In IE6 and IE7 message sending taken long time,

but receiving messages immediately.

in other browsers work fine.

Please help me.

Thanks

Hi,

how are you measuring this time? how much is the time difference from IE6 and other browsers? how is the configuration you are using? polling or stream?

I did some tests here and the sending time is almost the same on all browsers I used (take a look on the values before status code 200), 1ms at the mean.

do you really need to support those browsers? :)

Anyway, I don't have any difference on the code regarding browsers, only if you set to use some padding, what isn't necessary for IEs browsers.

Hi,
