Hi
I tried this from the book, but got an error:
@cache.action(time_expire=874, cache_model=cache.ram, session=True, vars=True,
public=True)
So i tried the ideas in this post and they had miscellaneous errors. I
thought things have probably changed since 2014.
Then i started removing parame
server-side it doesn't make any sense, so there's no native way to do it.
It's not going to be faster than serving a static-file.

I'm exploring options.
I want to be able to cache my images. Client side, server side it doesn't
matter.
What is the best method to go about this?

wasn't the original point just to add the proper headers ?
Of course you can't cache a generator (that is what response.stream
returns)
It makes no sense at all to store the actual contents of the file on
memcache

You received
Version 2.7.4-stable+timestamp.2013.10.14.15.16.29 recent enough?
It's after your original post.

I tried using the above code, but results in the follow error message:
cache.client(time_expire=604800, quick='SVL')(lambda: 0)()
AttributeError: 'Cache' object has no attribute 'client'
Am I missing something?

It works like a charm. I used the stream function and that works too.

ok. So, basically the problem is that response.stream is a "special" kind
of function.
It raises HTTP(200, content_of_the_file) instead of returning it, and
raising an HTTP(200) is a smart way to do it.
Unfortunately, this means that
def download():
return response.stream()
basically d
sorry for the misguidance unfortunately response.stream doesn't return
, it raises HTTP() so basically the cache decorator hasn't the possibility
of completing. I'm looking into it right now.

You received this message because you are subscribed to the Google Groups
"web2py-users"
So I changed my function to this:
#7days
@cache.client(time_expire=604800, quick='SVL')
def fast_download():
session.forget(response)
# very basic security (only allow fast_download on
your_table.upload_field):
if not request.args(0).startswith("db.Images"):
return download()
#
Now it works! I just changed the return function to return
response.stream(open(filename,'rb')) :D
Thanks folks!
PS: How to use @client-cache? :)

Hi Folks!
Thanks for your answers but my implementation is a little bit different so
none of the solutions above worked, I have tried to adapt the slice

cache.client (when no cache_model is passed) just sets headers (that's the
idea at the bottom).
When you pass a cache_model, it sets headers AND cache the results (and
that's the "idea at the top").
cache.client was created in the first place to avoid having to set headers
repeatedly.
There's
Does that work for download? Download returns a stream not a string.

there's a new @cache.client decorator to set expire headers in an easy way
as soon as the book gets updated the docs will be here
