urgent iOS internet issue (url request timeout setting?)

[Charles Warwick]

Hi Terry,

I think this is the same issue as has been reported here that I am 
looking into:

http://quality.livecode.com/show_bug.cgi?id=19656

At this point in time, issuing "tsNetLibUrlReuseConnection false" is the 
best solution, as this will stop tsNet from trying to re-use an existing 
open connection to a server.

If you are using tsNet functions directly, the equivalent option can be 
set by using tSettings["no_reuse"] to true and passing that to the 
function.  For example:

local tHeaders, tRecvHeaders, tResult, tBytes, tSettings
put true into tSettings["no_reuse"]
put tsNetGetSync("http://www.livecode.com", tHeaders, tRecvHeaders, 
tResult, tBytes, tSettings) into tData

Best Regards,

Charles

I’m not at all sure what this achieves but it seems that a new connection that can’t connect doesn’t experience the same problem as an existing connection that was previously successful.

If it is I proceed with the upload, if not I just save a local copy of the file. Anyway, the first time I do the test the request seems to take forever (minutes?) – which I don’t have (I need the request to be completed within a few seconds). The second time around is ok though.
