I am using the following to download images. Per Robert's suggestion, I am
going to parse the detailedresponse to check a few things.
<@assign request$URLContents '<@dom <@url location="<@var request$Image>"
waitforresults="true" detailedresponse="true" maxresultsize="128K">>'>
I put together the following to parse the xml. I was thinking that by
checking the Status Code and making sure it was 200 that that would indicate
the download was successful. Am I correct in assuming this?
In the event I am not provided with the complete file name, I want to check
the "Content-Type" so I can put the proper extension on the file when I save
it.
Is there a better way to accomplish this than the code I put together below?
Thanks
