[webkit-dev] Save Page - Ideas

[zaheer ahmad]

hi darin, dave,
thanks for your inputs.

i have few comments on the patches

1- 7211 - the patch seems to serialize only the html. what about external
resources? chrome seems to rely on the cache for these resources but this
may not work in case you want to use the save page as a feature to
store/view content offline.

2-7168 - this patch uses the archive resource which seems to cache all
resources loaded including external reference in memory. though i haven't
measured the extra memory, it could be an issue for resource constrained
devices. so storing to file system may be an option at the cost of little
slower load time?

thanks,
Zaheer
