QHttp Problem with many requests [Qt-4.3]
Message 1 in thread
Hello !
Is there a known error in Qt-4.3* (tried 4.3.1 and
4.3.2-snapshot-050907, Linux and Mac Platform) in the QHttp class with
many requests?
I use QHttp to look multiple webpages, for this I use a QStringList with
URLs and than I download every page listed in the QStringList.
If the QStringList has only 10 entries, every thing works fine, if the
list has 6000 entries, the following error occurs:
I don't know, where I should look know.
If someone knows the answer or had a tip for me, this would be great !
Thanks a lot for helping !
Best regards,
Heiko Steindl

Hello !
The problem was in my own code, it was not in Qt ! (It was very
difficult to find it)
Thanks a lot and have a nice weekend !
