I don't know if its possible but just want to ask if we can cfhttp or any other thing to read selected amount of data instead of putting whole file in CFHTTP.FileContent.
I am using cfhttp and want to read only last two lines from a remote xml files(about 20 of them) and read middle two lines from some text files (about 7 of them). Is there any way I could just read that specific data instead of getting all files because its taking a lot of time right now(about 15-20 seconds). I just want to reduce the run time of my .cfm page. Any suggestions ???
Hmm, not really any special way to get just parts of the remote files.
Do you have to do it every time? Could you fetch the files in the background, write them locally, and have your actual incoming requests just read those files? Make the reading of the remote files asynchronous to the incoming requests?
If not, and you're using CF8+, you could use CFTHREAD to thread out the various requests to run in parallel: http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Tags_t_04.html
You can use the "join" action in the end to make wait for all the threads to complete.
Edit:
Here's a great tutorial by Ben Nadel on using CFThread to parallelize CFHTTP requests:

There's something else, though:
27-30 sequential http requests should not take 20-30 seconds. It really shouldn't even take 1-2 seconds - so you may have some serious other issue going on here.
