Cache Error with downloadDestinationPath, Not storing downloaded data #211

merged 1 commit into from

3 participants


I fixed a problem I noticed. If you use the cache to store files and you are storing using a downloadDestinationPath, the cache does not correctly copy over the new data.

The next time you download that url, it will return the old data. The fix is to delete the file before copying over the old one.


Please integrate this fix in your next release. I had exactly the same issue. For now, I'm going to patch our local source of ASIHTTPRequest, but it would be nice if this patch wouldn't be gone after updating the next time.
