Title: WebService Content Length Error
Post by: debzidoodle on July 01, 2014, 11:30:21 AM

Hi Bruce

In NT 8.17, I have a webservice that returns a view.  If I have more than 2 records that return my Content Length is wrong in my header.  Here is an example of what I mean, the below XML is 1769 characters long, the content length in the header says its 491.  

This does not seem to be data specific, it appears I can use any combination of records, so long as it is less than 3.  If I have 1 or 2 records the content length is correct.

I attached the CLW, let me know if you still need an example app.

Hi Debra,

Bear in mind that the outgoing content is being compressed;

Content-Encoding: gzip

and so the content length

Content-Length: 491

is the length of the _compressed_ text, not the uncompressed text.

Are you seeing a problem in the webClient side of things?


cheers
Bruce

Thanks for the explanation, makes sense. :)  I was having an issue on my client side but it turned out to be unrelated

Thanks again

Debra

I did end up having to turn off the compression for dynamic data.  I am using a WinDev Mobile client, and it could not process the compressed  result.

Just FYI for anyone using web services, if you are having issues getting the data returned in the client, but you know the data is being sent... try turning off the compression.

if you look in the server log, at the incoming request from the client, what does the header look like?
