Hello Charter,
I inserted your code and tried spidering one website and for now it is working just fine !
It's great!
Thanks a lot!
I did not fully understood the chunk encoding stuff. I'm still french, so it will take me a bit longuer to read and understand all the informations you gave me to read

It seems to be a problem between the web pages I've made and how the server return them...
Anyway, thank you again !
