Is anyone using a RAMDisk with U2 files?
I have noticed that there are two types of ram disks within Linux - tmpfs
and /dev/ram1 which can be used to create a small file system.
Does anyone have any practical experience on these options?
Is there an effective option for MS-Windows?
Cheers,

Its expensive... and it seems fairly safe as IBM, HP, and Dell are all
selling it now...
Take a look at this:

It basically acts just like a disk from what I understand, except th
I've used them in development, but not in Production.
I am just about to post an article that includes usage; I just haven't had time
to finish proof-reading it.
For windows, check it this question:

Well I guess I should rephrase...
It is seen as another block device to the OS, Windows, Linux or what have
you.
So, in Windows it would be a drive letter.
In Linux it would be a block device that you could partition and format.
I have not personally used it, but, there are folks out there using
I mean using the existing RAM within the system to create and mount a small
file system which a temporary U2 file can be created and used; rather than a
complete SSD device.

Yes, but, "old school" ramdisks (i.e. creating disks in existing RAM),
aren't exactly reliable if something goes wrong (i.e. power anomalies, bad
memory block, etc.). So whatever you would be storing would have to be
temporary (which I guess you have already said), AND, you would have to NOT
care
I use the following scripts with our Linux system
[george@alpha mbin]$ cat mount-temp
/bin/mount -t tmpfs -o size=1G,nr_inodes=5k tmpfs /usr/tmpfs
(cd /usr ; /bin/tar xvf /usr/drive1/tempfsbackup .)
[george@alpha mbin]$ cat unmount-temp
(cd /usr ; /bin/tar cvf /usr/drive1/tempfsbackup ./tmpfs)
/b
keep in mind:
SSD drives have a limited number of writes (much better today than before)
tempfs do not (or at least I don't think so)
SSD drives however usually can store a LOT more than a tempfs file, which
depends on your physical memory - You couldn't create a 100GB tempfs
if you wa
It looks like you could do it in Windows 2000 Server natively...

Not sure what they did with it in 2003/2008 Server. They may call it a
"RAMDrive"

I was looking at writing a similar article/blog post as I am reading on
coalesced hashing at the moment.
I'll wait until yours appears.

I found the solution by myself!
The problem could be, that the functions 'setRequestHeader' und
addRequestParameter' are formatting the data in any way, that the
webserver doesn`t understand the request. When I logged the outgoing
traffic to port 80, I have seen valuemarks in the header inform
Karl - your original request said:
"How can I create the correct header?"
My mental response was "stop bothering with CallHTTP and use
cURL". I refrained from posting that because of the inevitable
retribution from people who prefer to bang their heads against
flaky software rather than just look

Karl,
I have used both setrequestheader and addrequestparameter without issues.
Add 3 parameters using AddRequestParameter:
sub httpPostXML
h = '';rh = '';rd = '';rs = '';sh = ''; pd = ''; sch = '';cf=''
URL = 'http://myuri'
boundary = '--':system(99)
z = createRequest(URL,'
But swap space isn't really memory, it's disk and nowhere near as fast as
memory, and (I don't know for sure) probably
even far slower than SSD's.
In reality, if your creating a tempfs partition for the speed of memory vs
disk, then using swap space defeats the purpose.
