I have a webservice and client in c#/dotnet and I am using EnableDecompression to gzip compress the responses that I get from the web server. Is it possible to compress the requests as well?

Are you pushing large data up in your request? If not, compression might cost you more than it will gain you. – Jason Jackson Dec 16 '08 at 00:17

Yes, we are trying to push up about 150MB of data in about 100 batches of 1.5MB... – horatio Dec 16 '08 at 00:32

SOAP extensions allow you to monkey with the SOAP stream on both the client and server. They're nice because you can leave your service code alone - manipulation occurs before a webmethod begins and after it ends. They work a lot like an HttpModule but can be included on the client/request side as well.

Other than that, the only option that comes to mind is manually serializing and compressing large SOAP elements as byte[], then manually decompressing and deserializing on the server (shudder...). The maintenance issues with this approach are likely prohibitive.

It looks like your 3rd link is just being redirected to http://searchwindevelopment.techtarget.com/?id=SOAPExtensions – Zack Aug 07 '14 at 16:10

@Zack - Yeah, the answer is almost six years old (!) and suffered from link rot. I replaced the bad link with a Microsoft article. Beware, SOAP extensions are not part of WCF and are therefore largely irrelevant. – Corbin March Aug 07 '14 at 17:53

I've found this tutorial on compressing SOAP messages in C#, using the SharpZipLib library and SOAP extensions:
Seems to garnish about a 30% compression, will be giving this a try today.
